OPINION - Rachel Johnson: Is London at war with its motorists? A sudden twist of fate changed my mind

This was going to be a huffy, hysterical rant about the so-called War on Motorists. Twenty mile-an-hour speed limits. Bus lanes that if you so much slip into for a second you receive a fixed penalty by return. The indignity of paying £100 for a speed awareness course after going 22 miles an hour — ie slower than a galloping yearling, faster than a horse and cart — through Penge, which I submitted to (and not for the first time — I find the courses oddly enjoyable).
