when does filtering become DWDC?

[Frosties]

You get used to it filtering into London and back on a daily basis. I generally stick to about 10mph faster than cars - that kind of speed I'd only not be able to stop if someone litearlly pulled out into the side of me. Tend to quit at about 70 and just sit there on the a roads i go into work on!

Apart from knackering my mirror on the arse of a lorry the other day (my bad) I agree with Joe....although there are times in London where "point & squirt" applies and others where 10mph goes out of the window on the basis of London's Mantra being "look after yourself and screw all others".
