Well I don't have one on my car and I'm not likely to ever own a car that does. Maybe people should try paying attention while they drive. I would be in favor of making distracted driving a criminal offense, or at least make the fine hurt. $5k for a first offense seems reasonable, make it a felony if an accident results, start throwing people in jail. Maybe people would start taking safety seriously and put down the damn phone. Automated technology to prevent collisions is not the solution, it is a crutch that enables people to engage in risky behavior. There is already far too much of this driver assist technology and driving isn't getting any safer, it's a proven fact that as soon as you take away the need to focus on something, the mind will find something else to focus on. When I was still working in the office I took the bus there and from my vantage point on the bus I would see people EVERY DAY barreling down the highway looking down at a smartphone on their lap, they think nobody can see them doing it. I have also nearly been run down in a crosswalk while someone was looking down at their phone. I don't want rounded cars so I hopefully bounce off and I don't want some gadget to hopefully see me and slam on the brakes (and the inevitable false triggers), I just want the person driving the car to watch where they're going! Driving is a privilege, there's no excuse for the carelessness so many people exhibit.
