How to make a complaint about a bus driver?

Bullshit, request camera footage asap and report to police informing them you've requested camera footage. If the driver veered at you it will be on film. All London buses are riddled with cameras. See older related posts/incidents.

Out of interest, has anybody managed to get any footage for whatever reasons before? The reason I am asking is because a friend of mine did a project about London buses a couple of years back and apparently the CCTVs are on a loop for about 2 hrs or so, so nothing ever really get recorded unless you stop the bus there and then to watch it. This was what he was told by the drivers who took part in the project... I have also heard sometimes the CCTVs are not even recording anything. Obviously, I don't know and I hope this is not true.

Also, I wasn't on the bus, so how would the CCTV help? Does it also record the road? And surely it's not pointing to the driver's booth?
