“Battery EV” vs “Hydrogen Fuel cell EV”

The Spark EV had more than 400 ft-lbs of torque putting it solidly in the 'muscle car' category. They tamed things down for the Bolt and later Spark EVs. High performance car, low performance driver, doesn't always end well, I guess.

My friend has a Spark, he got a good deal on it but he gets screwed by the licensing fee since the state claims it's worth almost 3 times what he paid for it. Amazing little car though, in terms of acceleration off the line it's one of the faster cars I've been in.

I would say the best solution for now is plug in hybrid - you get the benefits of EVs for shorter trips without having the problems EVs have for longer trips. Next step is to make the engine run on biofuel so longer trips can also be "environmentally friendly".

No natural gas, no electricity, no gasoline (retail pumps require electricity), no charging stations for your EV's (ditto, at least once the local batteries were exhausted). The lucky ones had older houses with functional fireplaces, assuming they could find enough stuff to burn. The even luckier ones actually had proper cold-weather gear to wear.

A large part of the Texas energy crisis could have been prevented if they had programs that paid people to disconnect from the grid and run on backup, as well as programs to reward greatly cutting down on usage. I had a setup to tap backup power from my car but didn't use it last February since it was way cheaper to charge backup batteries from the grid when it was up, even though that contributed to the problem. I'd imagine there would be a lot more investment in backup power sources if there's a chance of getting paid to use it.
There is one energy source that didn't fail, and that's home solar with backup - just brush off the snow and it's up and running. As far as I know, there's still only two significant manufacturers - SMA and MPP - that offer daytime backup without batteries. I'd imagine there would be a lot more if that concept were more well known.

A new plus for hydrogen coming:

Those "problems" are already mostly solved, it is not hard to get a full EV now that does 300 miles on a charge and can have a substantial amount of charge added in 10 minutes. For longer trips there are hybrids and conventional ICE powered cars, since most families have more than one car it's pretty easy to have an EV and a regular car or hybrid, or just rent a car for the occasional trips. Most people don't take road trips very often, I haven't done it since I was in my 20s.

I miscalculated once and ran out of gas. I walked to the gas station with a 2 gallon jug, filled it, and walked back to my car. That 2 gallons would take me 50+ miles, within the distance to the next gas station.
AAA (USA's largest motor club for road side assistance) would have come with a gallon or two of gas if I was members and called for assistance.
I think AAA (or the likes) has the capacity to carry a fuel cell should they decide to do so. They usually come in a small pick-up with other equipment, some including a generator for starter-battery and jumping. I doubt they would be able to come with large enough a generator to charge up your car for another 20 to 50 miles in short duration. In USA mid-west States, finding a common gas station in the middle of night (1am to 6am) can be iffy within 50 miles. I doubt charging stations will be more available than common gas stations any time soon.
I think the lack of an easily portable energy source is a huge disadvantage. In that context, fuel cell at least have some hope, EV's that is plug-in charging only has much less hope...
