I've actually found it makes driving safer for me, it's saved my bacon a couple of times.
I don't have any driver aids in my cars but I'm sure glad the people around me do.
Just this week driving down the freeway old mate slaps on the indicator and without even glancing in the mirror starts to come across. The car took over and stuck him right back in his lane the look of shock and surprise on his face was priceless. Not that he seemed to care, he even went for a second swing at it
Lets face it no one values driving standards anymore even on an enthusiasts forum like this you have to wonder sometimes.
