I nearly got sideswiped by a legally blind driver. The driver behind me saw what happened and asked "Was I OK". I said, yes as I anticipated him doing that. (not slowing down in time etc..)
She then went on to give me the helmet lecture. The one about how maybe it's safer to wear one etc.
Yeah as YOUR hairmit would helped the BLIND driver see you.
To me, that is up there with if you stay in bed no car driver will get you.
