Instant carma

What puzzles me about driving a car is that although I am normally one of the most impatient people alive, I get the opposite of road rage. Once I'm behind the wheel, music on, cigarette in hand*, a strange inner peace descends over me, which insulates me against all but the very worst 'traffic calming measures' that e.g. the London Borough of Waltham Forest** can throw at me.

* I'm not sure if this is still legal. It will certainly take the fun out of it when they ban it. I open the windows if the kids are in the car, honest.

** It's a good job I live out in Essex now.
