Thanks for sharing that. I know in my field ( trucking ) that nothing has changed since 1955 or so. Pull the body off a new truck and one from back then, and aside of the electronics, they are exactly the same. Used to be that you just kept rebuilding the truck and kept it for 20+ years, now at 500-650k you go get a new one, even though the engines and drivelines can go well over a million.

It's funny that the car that went 376 mpg that Shell built was based on a 1959 Opel wagon with no electronics.

Guess it proves we haven't progressed as far as we thought we have.
