EVDL Information:
It's been going for a long, long time. To mention just a few:
Too many people die due to not wearing seatbelt = seatbelt laws.
Ford Explorers roll over because of low tire pressure = mandated TPMS
sensors in ALL car tires.
Insurance companies paying out because so many cars are stollen = $$$ key
motors to work well is a
whole 'nother project by itself.

I gave myself an idea. Fill the battery boxes with a fluid. If the fluid is
leaking after a wreck, the battery boxes have been compromised, so the car
shouldn't be driven.
That's not a bad idea. Batteries also need heating and cooling. Fluids
are a good way to add or remove

It's just a game of cat and mouse.
A great summary, Klaus. And the cat has all the teeth and claws (money,

You'll notice that car companies have gotten a lot smarter in

amount of processor power necessary to control emissions and air bags. As
memory and cpus got to where they cost pennies, they realized that they
could control a lot more with them. They could make the dome light fade in
Sadly, due to my exposure to OEM representatives (auto makers), I can
safely say that they will cut every penny out where they can. For
