Ok, following the front wheel is the rear wheel. So they advertise this great new feature that detects a pot hole. So now the same people that can't go around a city block w/o GPS, can't monitor tire pressure, keep a safe interval between them and the vehicle in front of them while texting, etc, etc, Those drivers now also believe they no longer have to pay attention to road conditions. I can't wait for these self driving cars, to get some of these goofs from being behind a steering wheel. The second part when it fails what are the repair costs, and notice I mentioned WHEN it fails.
