At least @ianpspurs I wasn't as bad as my mother. She was really annoyed about some roadworks that meant she couldn't take the road she wanted to. So she stopped half way along the roadworks and asked some workmen which way she should go. They told her she must not stop because the lights were shortly going to change and she was blocking the road. She refused to move. The lights changed - the oncoming traffic started moving and there was absolute chaos.
