A common indoor building temperature range between 64 & 88 degrees F or 17.8 to 31.1 degrees C
In many locations worldwide the outdoor ambient weather conditions of air temperature diverges from these habitable temperatures. In winter for example the temperature van vary between sub 0 & just above freezing, or near fridge temperatures of 38 F or 33.3 C
Were I live about 10 miles east of Seattle, Washington, USA, the overnight low gets to fridge temps, while the daytime high in winter can hit 50 F or in spring can hit 65 or 70 F, but I only enjoy riding our HIBOY S2 PRO electric kick scooter or Segway Mini-Pro by NineBot or Honda PCX150 Scooter or MT03 Motorcycle or Crossroads Bicycle or LECTRIC XP 3.0 e-bike in fair weather, that would be around 65+ F & overcast, cloudy, not raining with dry pavement or dry cement or dry roads, not muddy, not wet, not slippery, nearby there abounds many new to driving low skill level motorists who are very dangerous to pedestrians, bicycles, scooters, motorcycles, even other drivers in cars or automobiles, driving heavy SUV with low skills far more likely to cause an accident or crash & I am vividly well aware of this as a School Bus Driver since I am out on the roads daily, not just commenting too & from work but also driving for work all day. '
Some people I work with say I am a thermal snob for not riding in cool or cold rain. That I am soft or weak for not riding in the rain, but I don't enjoy riding in the rain, in addition to understanding how hazardous operating a 2 wheel vehicle in inclement weather can be.
I have taken to telling such people "Look, I don't see you riding a bicycle or motorcycle to work, so why are you giving me a hard time about it, clearly you obviously either do not own a bike of any kind or I have never seen you use one to get too or from work, so why are you giving me advice about something you probably or likely know littler or nothing about."
M a coworker who only lives 6 miles from work started riding a cool E-bike too and from work, but got into a traffic accident with a car that caused him to miss work for 3 weeks to recover & he has lasting injuries & has resumed using his GMC Suburban that gets a staggering 10 miles per US gallon of fuel or 25.3 liters of gasoline per 100 kilometers. Our 2022 Corolla Hybrid gets 64 MPG or 3.67 liters per 100km by comparison. Megs 10 Prius III gets about 48 MPG or uses 5.88 liters per 100km. The Honda PCX150 gets 103 MPG solo or 83 MPG two-up similar to 2.74 liters per 100km or 2.8 liters per 100km. As you can tell going from 83 MPG to 103 MPG gives 20 miles more range, but in liters per 100km sounds like a tiny fractional difference between 2.74 and 2.8 which are mathematically similar as numbers. But fuel economy does not tell the whole picture. It's vastly easier to load something into the back of Megs 3rd Gen Prius with its giant lift back rear door vs the much smaller trunk lid of the Hybrid Corolla Sedan. On our other 2 wheel vehicles a backpack the only pragmatic way to carry goods, and we usually bring water, juice boxes, dextrose tablets, trees nuts in a ziplock bag, or other snacks, a foldable puff jacket with hood, gloves, pens, or seasonal specific or mission specific tools, whatever the occasion calls for.
When people are shopping for a car they often consider in this order
Price, absolutely purchase prices out the door or with financing in terms of cost per month
Features, as in ADAS comfort, utility space, ingress or egress or how easy it is to load or unload or get in & out of, or how comfortable the seats or ride quality are.
Style or look the 3rd most valuable feature people value, so the automakers tune the taillights to look more interesting to add sizzle to the metal box with doors & windows & an engine and motor, since all automobiles have a lot in common in this regard.
The differences between models of cars can come down to long term or total ownership costs which are strongly influences by reliability, costs of maintaining & insuring and repairing such vehicles. Fuel economy one of the last considerations in terms of what people value, though the Tesla Model Y offers the best value in the EV space, though we cannot make billions of lithium ion batteries to give more people EV's, for that we need batteries made of earth abundant minerals like the upcoming Sodium Ion batteries in pre-commercialization today.
How fast can this vehicle heat up & defrost if parked outside in cold winter a question with relevance to people who live in very cold locations like Alaska or Russia but has little value as a concept to people who live near the equator where it is warm or hot virtually all year.
Nearly all modern cars feature cabin heating, front & rear window defrost, air cooling conditioning that also helps with winter defrosting, can cool or heat rapidly when operating as in the engine is on or the vehicle is in the full on state.
This brings me to Van Life or Car Camping, something I actually do in the 2022 Toyota Corolla Sedan. How I do it. I added 4 inch thick foam to the trunk, cut to shape to fit it nicely. Then a big queen size fuzzy blanket & heated blanket that I plug into a battery generator with built in inverter & 512 watt hours of battery enough to run the electric blanket on full blast 5 hot for 4.5 hours. A 12lb lithium iron phosphate external battery extends the runtime to 9 hours. I bring a 3 gallon jug of water along, a bucket for going 1 or 2, a container of baby wipes, toilet paper, box of tissue paper, a portable fridge, a compact camping isobutane stove, a single low mass steel pot for cooking, a titanium cup, SS French press, pre-ground coffee, fuel for the stove, food in the portable fridge to cook, a bag of room temp items to eat also or as part of cooking. Also a bag of clothing with extra socks & underwear, tooth brush, floss, toothpaste, charger for Apple Watch & iPhone, backup battery & solar PV method for charging battery generator & portable battery pack, its for cool weather in spring or autumn, works in summer, can work on warmer winter days.
I basically sleep in my car like this with a camping pillow for about an hour at work on my lunch break if I am really tired for some reason. I have only ever practice like this for about 1 hour & have noted that the inside of the windows fogs over with condensation, so I have to crack a window to vent & the trunk while folding the rear seat down on the passenger side gives enough room just battery for my height. I sit in the rear passenger seat behind the driver side to take my shoes off then crawl into the opening to the trunk & flip over to sleep then jam the fuzzy blanket to block out light & hope there is enough O2 in the trunk for 1 hour of sleeping & so far seems to work.
If I were to camp all night like this I would install a window vent cover that allows gas exchange but keeps rain out, which can be done with plastic sheet & tape in a pinch, but many products I do not own are available for the highly popular Corolla Sedan that work as a window venting solution, or plastic window covers known as wind blockers that also block falling snow & rain. I plan a road trip in the near future where I will be using the car for camping solo.
Being a compact sedan, this is only practical for 1 adult as I am just shy of 6 feet tall. My wife Prius III can hold us both but not very comfy, a larger SUV like her previous 4Runner would be much better for car camping, but it only got 26 MPG & that was with mild hypermiling or fuel saving driving techniques. Our 04 Audi B6 2.8 Quattro gets about 24 MPG average, 19MPG driven harder faster, up to 40 MPG on highway road trips at 50 MPH energy efficiency focused.
