It's pretty hairy around Park Lane, Marble Arch etc because there's a lot of traffic. Cyclists can use the bus lane (where only bikes, motorbikes, buses and taxis are allowed) but when you need to get across the traffic to turn it's still hairy.

Other areas are less hairy because there's less traffic. If you're trying to claim that the blue stripes are less hairy there are a few spots along CS7 that aren't a whole lot of fun too.
