Lunch in Ewell and a couple of near misses

Cycled down to Ewell yesterday to meet my friend Tania for lunch, about 15 miles each way. On the way I got lost in Wandsworth again (am I missing a trick here?), though fortunately had a map this time. The return journey was pretty speedy, though 1) someone almost opened their car door on me - must cycle further away from parked cars in future - and 2) I experienced my first episode of cycle rage as a black cab pulled out directly in front of me while I was travelling about 20mph (That's right, 20mph. On the flat). I slammed on the brakes and dodged between the cab and the car behind, and wondered whether the driver of the car behind could lip-read as I directed profanities at the cab... On the plus side, I didn't get lost in Wandsworth.
