Please report dangerous drivers to the police - Roadsafe. Report to plod, not just whinge here.

I was cycling on a long straight road last night when a single-decker bus flew past me at speed and fairly close. A black unmarked car driving the other way wasn't happy about how much space the bus had left it. The driver tooted his horn in anger at the bus for a few seconds as it went past.

I thought that was the end of it. Normally it would be.

A few seconds later the car came screaming past me (at a safe distance) and tailed the bus until it stopped again.

Three police officers in full combat gear and anti-stab vests jumped out and charged to the front of the bus. One of them turned around as I caught up to the scene and asked if I was okay.

The bus driver looked absolutely terrified as they forced themselves onto the bus and started shouting about safe distances for cyclists.

One of the officers told me that they're normally on their bikes themselves, and tired of seeing drivers not giving cyclists enough room. They let the bus driver go, but this morning I watched the same bus company wait behind a cyclist on a road bike until it was safe to overtake. I wonder if the bus driver told his workmates about it when he got back to the depot.

I realise this will probably never happen again, but the sense of justice was brilliant. We need more cycling police officers - officers who understand the dangers of cycling, and realise that near-misses still indicate dangerous driving.

That bus driver will think twice before he overtakes a cyclist again, at least for a little while.
