... if you've run a red light unknowingly? What with highway hypnosis, it's not a detail you'd be able to recall later. I do know one time I had a passenger point out that I blew through a stop sign in front of a police station (it was a two-way stop giving the freaking parking lot the right of way over the actual road. Plus the sign was missing its reflective-ness) so, you know, shit happens.
