That really was a childish thing to do! Rush hour traffic, road works, on a roundabout, bumper to bumper, pissing down with rain, dark, and Mr RALLI ART decides to show off his dump valve. Nearlly lost it and wrote yourself of. Now that would have been even funnier! You even had a passenger in the car with you. What were you thinking?

Have a look at your surroundings before putting your foot down!

By the way, your dump valve is not as loud as mine!!
