Not everyone an automotive mechanic able to fix or repair or maintain cars, but in America or the USA where I live a car, truck or SUV about the only practical way of getting around. Public transportation nearby too slow, requires too many transfers, takes too long, a very hard problems to solve because of low population density urban sprawl in suburbia where there are many square miles of nothing but housing, mostly single-family homes that each cost over a million dollars now, but there are no services within walking distance of any of these homes.
Look up global vehicle accident statistics by country, millions of accidents happen daily, it only takes a second or less of distracted driving to cause an accident. When a driver uses a smartphone when driving it is 26X more dangerous that driving buzzed with a 0.08 BAC or blood alcohol content, statistically. Worse when the driver new at driving, a teen or young adult with limited impulse control, in cab other kids distractions, smoking pot, underage drinking, these are the most unsafe drivers statistically.
ADAS or Advanced Driver Assists include things like VSC vehicle stability control since the early 1990s, or early 80's in banned group B rally cars that became wildly high performance before the WRC changed the rules due to the violent accidents happening at the highest speeds achieved by two megawatt compound super turbo charged ultra-high performance engines made with aerospace tech in clean rooms by teams of engine engineers who port, polish, texture, optimize, tune, & some of these group B rally car engines were millions of dollars as a result of the insanity pushing a 2.0L 4 cylinder super + turbo boosted engine past 2000 horse power into a custom made sequential transmission pumping torque vectored power to front & real LSD exceptional AWD traction controlled master series rally car drivetrain technologies present in GR Corolla & GR Yaris widely available now incredibly.
ADAS have evolved with camera sensors, ultra sonic range sensors, radar range sensors, laser range finding, GPS, 4G LTE built into the vehicles main computer system, noting that new 2025 vehicles have an OBDII from the late 1990's can-bus interface connected to an ECU or electronic control unit which is networked to hundreds of other embedded heat sink cooled computers for anti-lock braking, automatic emergency braking, variable ignition, variable pulse width controlled fuel injection, to take signals from the exhaust temperature voltage O2 sensors, for emissions control & so the exhaust works with the catalytic converter correctly, to reduce fuel consumption & emissions, improve torque or power output, or something like Lane Keep Assist to help drivers keep the smart technology car centered in the lane between the white fog line to the right & the yellow lane separator line to the left, though it could be other colors or bumps epoxied to the asphalt for safety, such that if the tire hits it the bump causes a judder the driver can hear & feel in the steering wheel or cabin cockpit.
There are many autopilot like new ADAS functions and every year they keep adding more to enable LCD dashes with smartphone interface like Apple Air Play over blue tooth or via the dash mounted USB-A port charging cable attached to the smartphone, so you can listen to Spotify or Pandora in my case, through the car stereo or so that the GPS maps from your smartphone can go to the center dash display so it is easier to see & the voice over turn by turn instructions play through the car stereo, or so that you can make a phone call with your phone with the car stereo without touching your phone amazingly. I know about this stuff because its present on my 2022 Corolla Hybrid LE & I have read the instruction manual several times to learn all about the Toyota Safety System 2.0 present in this vehicle model & year.
A camera system integrated into the top center of the front windshield enables RSA road sign assist & displays the speed limit the system sees onto the dashboard where it persists so that you can read it easily if you did not see the sign when driving by it. I happen to really like the Road Sign Assist technology. When you put the PRNDB shift selector into R for reversing it turns on a backup camera integrated into the handle area of the trunk lid with a wide angle lens, which sends the imaging to the center dash display so you get a clear view of what is directly behind the vehicle, while digitally imposed lines on the display streaming video of backing up to show you tracking & distance lines to help you park easily.
On more advanced versions of Toyotas ADAS, they feature Bird View which stitches images from many cameras to show you a top-down view as if you are looking directly down at the top of your car with enough wide angle to help you park with sub-inch level precision amazingly. Other cools tech on other more advanced ADAS on more expensive models' projects HUD driving information onto the front windshield, so you don't have to take your eyes off the road to get essential dash information like vehicle speed since controlling you speed important for safety & legal operation on public roads.
If you are replacing tires, upgrade your tires to the best ones possible. That is the control interface between your vehicle & roadways that gives traction important for handling, acceleration & braking so you can steer away from hazards faster while maintain control or slamming on your breaks & stopping before running into anything with better stopping distance enabled by higher quality tires. Tires are an upgrade that many people overlook when tuning for performance. Maintain the correct tire pressure embossed onto the side of the tire and fill the tires with more pressure as needed after the vehicle has been parked overnight so the tires & gas inside cold or room temperature. When you drive flexing & friction heats up the tire & gases inflating the tire, so hot tire pressure higher than cold tire pressure.
Safety focused driving can include mild hypermiling or driving cool calm collected, steady acceleration never rapid, always predicting or thinking ahead to keep inertia, to waste less fuel & produce fewer emissions for no guilt safely efficiently driving smarter with more applied deliberate intentionally focusing on safety then fuel economy maximization, then comfort, which is often improved with smooth calm driving anyway. If you drive more gently your vehicle will be more reliable, use less fuel, tires & brakes will last longer & it will emit fewer emissions & save you money in several ways. Higher speeds & rapid acceleration produce more wear on the vehicle, more NVH for the occupants, & in general are more hazardous or dangerous because high speed accidents cause more harm or are more deadly, in many accidents the people hurt are left with lifelong painful suffering disabilities from the injuries caused by the accident.
In many American suburbs there is no grocery store, no gas station, no stores at all, just houses for as far as the eye can see. If I leave my home on foot it takes almost 20 minutes walking down the giant mountain to get to a gas station, the closest business open to the public where they sell edible UPF items & few things that could be considered healthier, but mostly junk food or snack food made with industrial processing technology in ways that are virtually impossible to do at home in a normal home kitchen with ingredients a normal person would have at home, such as any of ten thousand different chemical additives, which is part of why we call the western industrial dietary diseases of civilization a diet based healthcare debacle of excess sugar, salt, trans fats & chemicals added to improve shelf life and or simulate colors and flavors of real food they were inspired by, noting that after industrial processing & adding artificial chemical additives these UPF ultra processed foods have almost nothing in common with any food eaten by people or animals in nature for thousands of years.
It was really only after world war two that chemical weapons were converted to agricultural chemicals for pest control that industrial farming, fertilizers, herbicides, insecticides, fungicide & pesticide began being applied to food crops, then this sleazy scientist taught the food processing industries of America how to use Bliss Point Engineering to make Ultra Processed Food designed to be additive with analogs additives of popular drugs of abuse added to make them so that "once you pop the top you cannot stop until you eat the entire container" making it very hard to control servings consumed because some of the chemicals added block Leptin the Feel Full Hormone & increase the release of Hunger Hormone Ghrelin.
The food processing industry actually using the same kind of chemical tweaking of UPF that the Tobacoo industry has famously done in the mother liquor sprayed at supersonic speeds as pressure jet to embed nicotine mod chemicals into the fluff & reclaim & rag tobacco strips used to make the filling of the cigarette, then other additives & chemicals in the cigarette paper & filter are used to further modify the smoke to make it even more addictive & damaging to the health of the person who unfortunately smokes this UPF tobacco product which is very different than smoking real tobacco out of a pipe or in a real handmade tobacco leaf cigar.
In the same way a homemade baked good made with 7 ingredients vastly different that the commercial UPF snack of the same kind that has 26 ingredients including chemicals that normal people cannot read or understand & have no ideas what those strange chemicals listed in the ingredients do or are there for or if they are even safe to consume, probably not since they are designed to improve shelf life, block leptin, increase ghrelin, and act as an excitotoxin with glucose toxicity from the resulting high blood sugar formed after eating such junk foods with weird chemicals added.
Many people in America are suffering from brain fog, mental problems, because they have uncontrolled type 2 diabetes from eating a diet of mostly UPF garbage & junk food, candy, soda, trans fats, excess sugar & salt, unhealthy omega 6 rich oils that oxidize producing artery hardening AGE advanced glycation end products which is like eating toxic waste in a way.
Incredibly 72.3% of what Safeway the grocery stores sell to Americans not real food, but industrial ultra processed food proven to be the major cause of the diseases plaguing America & people in other countries who have adopted the dietary excess disease of civilization industrial UPF snack & junk food died which is also causing the kidney failure epidemic, dehydration, neuropathy, strokes, clots, embolisms, heart diseases, ADD & ADHD, dementia, Alzheimer and lymphatic cancers seem to be strongly attenuated by excess blood sugar levels from eating industrial junk & snack food based diet excess.
In this way, many stroke victims are dangerous drivers. Many people with uncontrolled high blood sugar are dangerous drivers. People intoxicated by eating excessive amounts of UPF chemical additives are dangerous like drunk drivers, the high blood sugar causes brain malfunction by damaging the glial cells & neurons progressively reducing mental function as the blood sugar increases to unsafe levels & at very high levels can cause a diabetic coma & complete loss of consciousness, making safe driving in such a state completely impossible.
