Not sure whether this deserves its own thread, but I'll leave it here.
This is a serious warning.
I was riding around town today, and the Olympic vehicles have arrived in force, all over the place.
The warning? There are a huge number of out of town drivers, driving all manner of vehicles, especially "official" buses and coaches - some from as far afield as Eire - foreign cars, all sorts. This means that there are an unusually high number of drivers that are NOT be used to London traffic, roads and cyclists. I've had a couple of unusually close passes from coaches, seen drivers peering at the roads, obviously lost, been asked the way to Victoria station in Proctor Street High Holborn by a bloke with a broad Scots accent (I told him, but don't rate his chances). There's a kicker here - even when they have satnav, the changes for the olympics are going to make it ... interesting. (eg, no right turns off the Embankment westbound at all !!)
Be careful out there, take extra care, please.
