Gas cars need a jump all the time.

If this is really an anxiety of someone’s, they can carry a capacitor in the back sufficient to be charged somewhere and take the vehicle to a charger. That should work in 90%+ of situations.

All the time? That's some strong exaggeration there. Last time I needed a jump start was in 2016 and before that.. can't put an exact year to it but it was back in the 80s.

Please describe in some detail how you expect this to work? Can you link to this "capacitor" that people should buy that can do that?

As in it's frequent. I'd estimate about as frequent as someone running out of charge in an EV nowadays.

(If you're in a hot climate, e.g. Arizona, and park your car outdoors, it literally can be every year or two.)

Apparently they're still marketed to commercial users, pricing in the $5k+ range. EV to EV charging, emerging on newer vehicles, would be the analog.

In my family's 20+ years of owning multiple vehicles I can count on one hand how many jumps we've needed, and they fall under the category of 1. old battery or 2. left some lights on.

The latter wouldn't even kill the battery any more.

They also sell portable jumper battery packs for like 60 bucks. We got one because our car battery got terrible during COVID, when we barely drove it for a year or more. I've never had to use it, but it's nice to have in case the need ever arises (and it can be used to charge electronic devices). It stays basically 100% charged for surprisingly long periods of time.

Do these exist?

A quick Google turns up this kind of thing [0] which, based on the price point and form factor, is aimed at tow truck operators rather than individual drivers. Costs $10k+ and will take up most of the back of your car.

Yes, they do, and it's available as a service in Australia:

That's a commercial unit again, not something you throw in your trunk.

That's probably the right solution to this - and something every tow truck will carry in 10 years - but it's not the "capacitor in the back" analogue to an empty jerrycan.

Errr that's a few minutes at most to fix, and once the car is started, the battery is no longer necessary. That's a fundamentally different thing to a dead battery in an EV, where the battery is essential to the propulsion system.
