Have you reported him? Especially as you have witnesses.
He does not sound like the professional driver he should be. There are a lot of unprofessional Taxi drivers out there - the rest of us rely on victims such as yourself reporting poor behaviour...
Another who does a fraction of the speed limit getting nowhere near it.
Nothing ahead, hasn't just pulled out of a junction. Driver is just going slow for no reason.
50mph road & they're hovering around 30-33mph.
Help me find this car
