Speeding, reckless driving, running red lights and stop signs is absolutely rampant where I live and people really do die because of it.
I'm tired of entitled assholes thinking that they can drive however they want, endanger everyone around them, and that they just have the right to do that. Even if they don't value their own lives, we value ours.
So I strongly support red light and speed cameras, traffic calming, and physical pedestrian and bike barriers. Not sure sure about cars self-reporting, only because you could just buy a different car. There is a pretty strong argument that cars have no need to be able go 50+ mph over the speed limit like they can now.
