Hadn't mentioned it on here before but last month I was fortunate enough to be a bit slow moving off from some lights in the west end. Had I been my usual 'off on amber' self I may well have been hit by a No 6 bus whose driver was paying more attention to his phone than to the traffic lights. Happily I was able to get the number and a note to the operator followed. It took a while (and for some reason they seem to have taken 3 days to receive my email), but I did get a positive response...
I am writing in reply to your email of 2 July 2012 to London Buses concerning an incident you witnessed involving a Route 6 bus on 29 June 2012.
Our policy is to prohibit the use of mobile phones by drivers, whilst on a journey. Staffs are regularly reminded of their obligations to obey Company rules in this respect, as the practice is illegal and dangerous as it causes a distraction. You can be assured that appropriate action will be taken against the driver concerned. In addition a reminder will be issued to all drivers on this particular subject.
I should like to thank you for bringing this matter to my attention.
