Another lovely thread! First time in control of something with 4 wheels was the traditional DIY-built wooden go-kart, built from spare wood in the shed and proper old pram wheels. Launching from the top of the hill at home was swiftly followed by the brake snapping and a high-speed entry into the garage block at the bottom of the hill....The Mk2 had better brakes.....
First time in control of something with an internal combustion engine was aged about 11, learning to drive and then driving the tractor at the Gliding Club, to retrieve the tow line after each winch launch - was a great introduction to the whole thing, on something that was really difficult to break, and got me a couple of free flights every day I did it. Thereafter, it was after I'd reached the grand age of 18, as Dad wouldn't let me near any of his cars!
