Guy driving this car suffers from a serious case of little man syndrome. Undertaking drivers over the speed limit then matching drivers and staring at them.
I get why he was doing it. He was trying to give a lesson to the people idling in the middle lane but a) that's not his job and b) he broke two laws doing what he was doing.
Dangerous driver... doesn't like the fact that you're sticking to the speed limit and doing 40 in a 40, tries to overtake and forces other drivers to brake suddenly! Dangerous cab driver...
It's the SacconeJolys car!!!
