the inherrent problem with these safety features....such as traction control, abs, auto stop, lane holding, sleep alerting, etc, is that people are not using them as they were intended.
these features are being used as crutches. people are braking later(especially girls), they're getting in their cars when they're too tired, and depending on the car to steer them straight, they're driving in conditions that they shouldn't be out in, and in none of these situations are the safety features intended to replace your own driving skill or knowledge. these things are meant to be there, and in theory, never need to be used....but they are there if you have an "oops" moment.
with these things, a lot of people aren't taking the time to teach their kids the basic skills that they should have when they drive. when you see a kid driving a honda accord, and he or she takes a turn pretty much the same way a 53 foot tractor/trailer would take it.....there's something wrong there.
