Modern cars, SUV, trucks, passenger personal vehicles often come with wireless no-touch key fobs.You have it in your pocket or purse or bag or backpack or satchel & walk up to the car door & it unlocks.
You get into the car & press the start button & your off on your vehicle journey without every touching the key. You get to where you are going, press the start button to turn the car off, get out of the car, then touch the spot on the door handle to lock it, again never needing to touch your key.
Some newer cars have a phone app to act as the key fob, but then if you use the phone app & have or get malware on your phone, a hacker can remotely disable your car, can control your car, can create a denial of survive so you can't unlock or use your car.
Put your key fob into a metal box at home, at work, at the office, when you're not using your car. The metal box acts like a faraday cage to prevent criminals from sniffing your key fob signal & then using it to program their ACDC universal car fob to steal your car or the stuff inside. Car hackers use signal amplifiers & dishonest companies make & sell them special air snort hardware to enable hackers to hack smart fob vehicles & vehicles with Wi-Fi computer data system that enable unlocking with your smartphone.
Do Not Use Smartphone App to Unlock Your Car
NEVER USE SMARTPHONE APPS TO UNLOCK YOUR CAR! It's a major security risk because of pervasive hidden malware on many people's smartphones, that they do not know about. Right now, its stealing data from their amazon shopping cart, their online banking, their contacts lists, but if a hacker gets ahold of their newer car with the car smartphone app, then the hacker can hack the car, often over the internet from somewhere distant around the world.
Malicious Software Hops Over Wi-Fi Connected Devices
Malware possibly on your laptop or tablet or Wi-Fi network at home can get secretly side loaded into your smartphone or smartwatch without your knowledge. Then it works with the cars Wi-Fi & installs malware on the newer automobiles where the ECU also has a 4G LTE modem connected to the automakers data network the entire time the vehicle exists in working order energized with a working car battery & electrical energy to energize the vehicle chips & compute & radios.
New Cars Lack Data Security
Modern chipset heavy cars with OBDII do not have a hardware-based firewall or malware protection. In cars where the dashboard computer controls everything like a Tesla model BEV, this malware can cause all sorts of problems. Rolling data centers, emergent EV's, HEV's & PHEV's & even ICE vehicles have hundreds of onboard compute modules connected with complicate wiring harnesses & lots of copper wire to enable the 12vdc to move around mostly with minimal voltage drop loss & good signal or power quality.

12 volt Automotive Batteries
The engine alternator or DC:DC converter keeps the 12 volt vehicle battery charged (usually a lead acid battery, PbA or SLI or AGM) and this type of battery even in EV's to act as an energy buffer for all the 12v devices on the vehicle. This is because the voltage of the hybrid or EV or PHEV traction battery often 200 volts to 800 volts, so this has to be stepped down to 14.2v to charge the 12v battery. All the lamps & bulbs & blower fans & compressors & other electrical pumps & motors for accessories operate on 8 to 16 volts DC from the car battery.
This means while your car is parked, the 12v battery has a persistent drain even when the car is off, since they are never really dark off.
The security system & blinking red security light & key fob listening system are always on. The ECU & data upload system usually locked on continually too. The compute system do go into very low power modes when the vehicle turned off otherwise the 30-80lbs or 20-50kg 12v automotive battery would be drained to 0% charged or completely discharged in less than 24 hours. You would then need to manually unlock the car to gain access to the battery to use a battery charger to recharge the 12v battery to make the vehicle useful.
Imaging your windows rolling down without your control while driving through a winter blizzard, that could be deadly.
The criminals sickos who do these vehicle hacks do not care about you, don't care if they hurt you, and actually enjoy causing people with more money than them or nice cars, to experience pain & suffering, since car hackers believe you are living a privileged opulent life while indirectly disenfranchising other people like them, through participation with large monopolistic companies like Amazon, or Alphabet or Tesla Motors which is actually a data company.
Tesla Motors a Big Data Company
Tesla BEV are more of a AI training data making, since the Model 3 or Y or S or X are more of a mechanism to put all large quantities of data Aquisition sensors out onto roadways to train autopilot AI generative mapping & vehicle control data systems. Tesla sells this autopilot control system data to other automakers eager to ingrate more sizzle ADAS features into their next generation vehicles to help sell more cars & SUV to new car buyers who value the latest technology, who also have the money to buy bleeding edge high tech expensive vehicles like a dual motor Model Y performance edition. Be forewarned that Tesla EV battery pack is fading away with cycling & time.
Shallow Cycling Improves EV battery Life / 30-80 long battery life mode short interval charging.
EV batteries have to be kept between 30-80% to last a long time, but most EV owners constantly fully charge them. Charging lithium ion beyond 90% causes accelerated capacity loss or lost of driving range in an EV, and the problem of overcharging accelerates capacity & range loss continually over time until the EV battery pack is fried & needs to be replaced.
EV Fires via Overcharging & Accidents
Sometimes when these EV batteries are mostly fully charged & the vehicle gets into an energetic accident, the puncture & shorting of the EV battery causes a very hard to put out fire that destroys the vehicle. Tesla actually installed titanium protection plates under Model S when this problem became a big public debacle.
Tesla Motors Collapsing
Now Tesla in a fire sale, selling their BEVs for 25% to %40 off prices to stimulate sales that are declining because the US economy is going off the edge of a cliff because of currency inflation & a failing mortgage market debacle worse than 2008. This will cause huge negative harmful disastrous waves of economic & social chaos around the world, since most modern economies embraced fragile fiat currency systems after the 1960's.
USA Economy Radical Downturn Emerging
Public disapproval of governments will surge as crime spirals out of control. Solvency of the governments collapse & the shut down operations. The income tax collected can not longer service the interest of the nation debt, so a currency renumeration enacted. This happened in Mexico recently, with the New Peso. The Israeli New Shekel also renumerated, since the old orignal one was based on gold coins. Gold is real money!
Gold Real Money Back Then & Today
In the time of Christ Jesus an ounce or 28 gram coin of gold could buy a really nice set of premium pharisee clothing full body garments, handmade pair of leather sandals superior to Berkenstocks, and a hand forged sword or dagger. In the Middle Ages the same 1oz or 28g gold coin could buy a complete set of body armor, hear to toe, with nice all leather boots, and a hand forged sword & shield. Today the same 1oz or 28g gold coin can buy a really nice set of clothes, shoes & a gun & ammo. Thus the gold coin had as much buying power back in the time of Christ Jesus, all through history as it does today in 2023. But stupid inflation prone fiat currencies have unstable constantly diminishing buying power over time because the state increases the money suppply to try to stimulate the economy, but this never works & makes all the money worthless. During WWI the Weimar republic issued increasingly worthless bank notes or fiat currency that eventually lost off of its value to buy goods or repay private or public debts.
