Never.
Was at very large intersection, as first car. My light turned green, I looked L then R, as always do in that particular situation, & here were TWO cars coming through THEIR red light, to my R, like bats out of hell!
I looked at driver to my L, who hadn't moved, because I hadn't moved, & we both shook our heads' simultaneously. He'd a grateful look to me, as if we had've moved we BOTH would've been wiped out on OUR R sides, as those offending cars were in a lane each, side by side...........
Very, very scary!
