Fast charging is vital. Sure, 99% of the time you don't need it,

Another way to measure success is when the number of fatalities from
autonomous vehicles becomes less than other vehicle fatalities. There
will always be fatalities but when your risk is less in an AV, why not ?
I've seen several mentions about accident rates, but that is misleading.

If that's really true, that's an incredible statement on how much energy
we're wasting. It says, effectively, that we could power 100% of our
auto usage with the energy only used to *produce* gasoline. Not sure how
much more would be needed for public transportation, short and long haul
freight
Very interesting idea. Would it be possible to design something that
allows that transition: to and from rails ? It would need to be able to
make the switch in a few tenths of a second in order to respond to
emergencies. I've seen the track work trucks which have rubber tires and
steel wheels t
truck only needs
enough batteries to get to/from the highway, 1 ton will probably be sufficient
(since it can charge them while on the rails)
