Every time I go into Bristol I witness an incident involving a scooter.
While I typically always have a camera rolling when I am on my motorcycle. I don't when walking or in a car. But this trip I thought I would just in case there was an incident and I was not disappointed. Only drove through the city for about an hour.
It's a good idea to not get right up behind any vehicle, but certainly not one without a clear view of behind them. If you cannot see their mirrors then they cannot see you.
