AFAIK some automakers also cut down on the number of sensors by doing stuff like reading the already implemented sensor(s) for the ABS to provide the tire pressure warning function.

That becomes circular logic because ABS is also required by law

Eh, you really don't want a car without ABS, though. For motorcycles, I kinda get it since you can't do some stunts with ABS, but on a car, it has zero benefit nowadays. Mandatory ABS, seatbelts and airbags would be the big things for me, followed by sexy, modern ESP, TC for powerful RWD cars and collision warning beeper (no autobrake at high speed, that shit's deadly and I hate that it can't be permanently disabled separate to the beeper).
