Interesting thought. We may be a few years away from it becoming mandatory equipment. The cost of the technology would be prohibitive in economy cars right now. Right now the option costs $1200 in a Ford and $4300 in a Toyota. if your buying a $20,000 car that tech bumps asking price almost 25%If this technology could really save a lot of lives simply because of preventing asleep at the wheel accidents, it should almost be mandated that all cars have it. Just like how seat belts were once an option, and then they became mandatory.
