What's this 500mile capacity battery going to weigh? A ton?
Literally?

50 miles, probably. But there won;t be much esle of any weight in an
elecric car.

Right. So the impact resistance WILL be thrown out the window, then?

There is a way we can, in one move:
- throw impact resistance away
- improve safety
- make cars much cheaper to buy and run, and more energy efficient
- reduce congestion

How implementable it is is up for debate. The mthod is to permit
go-cart sized vehicles, using their own fenced off lanes separate from
full size cars. These are safe enough if kept physically separate from
cars and trucks, and big enough for town trips, shopping, school runs,
small deliveries, and a lot of transport in and around towns. Of course
they wont replace todays cars, but for many people they will be all
thats needed. A percentage of our car stock could be replaced with much
more efficient machines.
