If they were really concerned about public safety, they'd focus on red light runners. I'd much rather face a car on the interstate going 30 over, than get T-boned by some idiot who thinks that he can beat the light - OR get rear-ended by some yahoo who thinks *I* should have run the red light so that he could, too.
I actually had a guy get out of the car behind me at a stop light threaten and curse me for not running the light. I put mister Kimber (still in holster) on the dashboard, didn't say a thing to him, and he shut up.
