I would drive a go kart down the street if it could do what my cars do.
I did that! My son and I built an Electric gokart, that we drove down the street. Neighbors didn't complain as there was no noise. Doing donuts was fun!

Even if there are superchargers in all of the places they are needed my question is this:
How many EV owners have had to wait for a vacant charger and for how long? If someone is ahead of you are they notified when their charge is done? And hopefully they will quickly come move their EV for the next person.
I've never supercharged but the closest supercharger to me I sometimes check out the status online. There's 4 stations, high water mark I've observed is 2 people charging.Even if there are superchargers in all of the places they are needed my question is this:

AC takes very little energy. Seat heaters the same. Using the heater consumes much more. If I lived in ice country I might not have a Tesla. I don't know.
That's interesting. I don't know much about auto air conditioning, but a comparable boat air conditioner (12-15,000 BTU) will probably pull about 10 Amps at 120VAC, or 1,200 Watts. So I would have guessed running AC has a real impact on range. It would be interesting to see the specs on the Tesla AC system.
An AC takes quite a bit of energy to run, but it is small compared to what it takes to propel a car. A car going at 60 mph on a flat ground may draw 18 kW. That's 15x what the AC takes. And the AC may not have to run full blast if the car insulation is good. And not everybody lives where it's 120F in the summer.
In a modern automobile, the A/C system will use around 4 horsepower (3 kW) of the engine's power
It takes about a 1/4 HP to run it on low on a cool day to over 10 HP on a hot and humid day...so about 180 to 7000 [Watts]
People do not realize how cars are such energy hogs, whether ICE or EV.

Good thoughts. We have a Wrangler Rubicon for going off in the wilderness and a Tesla for the roads. If I need to rent a vehicle, for a trip, I could but I'm not sure what you vehicles I'd be willing to drive after driving an EV. I'd prefer to consider level 2 stops to extend range rather than drive ICE.Lots of questions on frequent charging - as I understand it this is not done due to range anxiety but because the car charges fastest mid charge range. A battery can’t charge as fast 0-10% or 90-100% as it can 45-55%
Also current max charge rate is 250kW and I believe they are going to go WAY past that with their tab-less batteries. I believe the space will be very different in a few years.
As to cars - every family I know has 2 cars. Maybe if you are single don’t get one? But I don’t understand the need people are saying that you can’t have an EV because of all the long distance trips you take. We take a couple trips a year and we can use the gas car for that?
Based on my reading, the 90:10 ratio matches what I have seen in owners forums. This isn’t about environment (even though that is a plus) but because of how fun these cars are to drive.
It's interesting that EV car owners usually say they can't stand the smell of gasoline that is associated with ICE cars. For the record, ICE vehicles and gas
station dispensing pumps have been equipped with robust vapor recovery systems since the early 1980's. No smell of gasoline pumping gas or from your car, parked or driving.
Pretty weak reason in favor of EV's.
Any gas station experience in SoCal reeks of gas fumes. Aja set up a poll. I know what everyone is going too say.
I think hybrids are a great solution to EVs.
I don't think I will live long enough to see an EV motorhome, or if it is even affordable.
Heck, I have not even seen a hybrid motorhome, or even talk about making one. And come to think of it, why there have been no hybrid trucks or delivery vans? It seems to me that for stop-and-go driving, a hybrid vehicle would save a lot on fuel.
Yet, people go directly to EV. For example, Amazon bought 1800 electric vans from Mercedes, and ordered 100,000 electric vans from Rivian. The Mercedes vans are already in use, and Amazon just got the first few vans from Rivian a couple of days ago.
I don't know about the range of these electric vans, but I suspect that they are not good enough for use as a motorhome.
The range for most motor home wouldn't be a problem but yes charging could be an issue. I've read quite a few people who utilize campgrounds for traveling in an EV. For them a 30 amp service is fine. A larger motor home would require much more battery and charging capacity. Not impossible but probably expensive for now.A couple thoughts about an EV motorhome: the way we travel is to drive about 200-350 miles each day. Mostly we travel 1200 miles over a few days then park at different campgrounds for a week or a month over the summer. We do take a few local trips for a week or so.
The issue would be when we do park we usually have 2 air conditioners running, electric water heater, microwave, etc. all going. Will there be enough available power to also charge a HUGE battery while we are parked for 12-16 hours? Providing the additional power would be a major infrastructure expense for most campgrounds. I don't see this happening anytime soon unless you're talking about a small class b van type camper.
These stations take about 20 minutes to charge to 50%, 40 minutes to charge to 80%, and 75 minutes to 100% on the original 85 kWh Model S.

... Tesla sends a notification to your phone when your car is nearly done charging. I have mine set to 80%, the car stops charging at that point. If you are at dinner or shopping and you get the notification, you have 5 minutes once the car is fully charged to move it, before you get billed $1 per minute. This keeps people from blocking others.....
The fines that most child-care centres now charge – typically $1 per minute – to discourage adults from being tardy may actually promote lateness, researchers have found.
"Certain cues can switch moral behaviour on or off," says Samuel Bowles, director of the Behavioural Sciences Program at the Santa Fe Institute in New Mexico. "Charging for things often switches off moral behaviour."
Bowles concluded that fines can undermine a parent's sense of ethical obligation to be on time for the teachers. And lateness becomes "just another commodity" to purchase.

I couldn't disagree more.
The limiting factor isn't the batteries, it's the grid. I work for an electric utility and just chuckle when people talk about 500kw, 750kw, or even 1MW chargers and how they will solve the charging problems.
Even the largest cities electrical grids can't handle those kind of loads popping up in random areas and for random amounts of time. If they started TODAY in preparation for those kind of loads, even in tiny amounts, it would take years and insane amounts of money to be able to handle those load profiles.
Its not a case of having the technology available, tossing up a charger and plugging it into the nearest transformer...we are talking about a complete redesign of the grid and system wide overhauls, not to mention that the demand charges of those kind of charges would require 24/7 use to make it even close to financially viable, if at all.
