Have any of these hackers crash tested their vehicles?

I wonder what a rear end collision into a rear end filled with wet cell
lead-acid batteries would do?

Also, where exactly is the electricity for these things supposed to come
from? My home electric bill in the summer here in Northern California
already is getting close to $500/month when the heat waves hit, and that
is with solar energy taking care of all of our domestic hot water.

I really do not want to buy expensive electricity from PG&E for my
automobiles as well!
