What about self-charging EVs? These are the ones that just use regenerative braking to give a boost to MPG. No plug in at all.

That is the only type of EV I would consider. The batteries that support the regenerative braking are small and don't add that much weight to the car. I imagine they are also much less of an explosion hazard.

Pretty sure almost every EV has that capability. It's not anything special - when you slow down, the car is pushing the drive motor so it acts as a generator, and gives back a bit of the energy you put into accelerating. Instead of creating a bit of heat, you generate a tiny bit of power.

And they don't have special batteries, they just feed power back into whatever your main battery is.

Even better if it just charges up the lead acid battery which are not known to explode that often.
