[quote=Charger727]Rented a Mustang last year, I thought something was wrong with the steering, until I realized it was the lane change warning system shaking the wheel whenever I crossed over a lane marker

Thank goodness I could disable it!
[/quote The first time I drove one of those cars it took me a while to figure out what was going on. It just gets annoying after a while when you turn the wheel one way and the car tries doing something else.. I don't remember which brands these were but there are some that won't start if the door is open, and some others won't start until the seat belt is buckled. Something else GM does that had me wondering for a while is if the keys are left inside the car when you shut the door the horn beeps a few times. I guess it's a good reminder but it makes me start thinking I locked the keys in when I walk away.
