Computers
Noise-cancelling headphones
Mid-80s Buick Riviera/Olds Toronado. They had touch screens in the dash, almost 20 years ago. It used electronics to do all kinds of things that normal people would either not notice or consider pointless, but I think are cool. For instance, if it's light out (as determined by a photocell in the dash), it doesn't turn the dome lights on when you open the door, since obviously there's no need for them during the day. A friend had one, and the oil pressure sensor went bad. At first the screen displayed a "low oil pressure" error, but after driving for 50 miles or so the computer realized that there's no way it'd still be running if there really was no oil pressure, so the message switched to "electrical problem detected". With those kinds of details, I'm positive those cars were largely developed by aspies.
