90 quids in fines in two days

What's with police in vans shouting at people?

I got shouted at by police in a van when I was riding in circles at a red light. The cycle box was fucking huge, I could have ridden round and round all day long.
The only reason I was doing it anyway was so I didn't get stopped for going through the red light.

Probably reduces the guilt from not getting outside of the warmth of the cabin..
