I'm what was called 25-cent (in swedish currency though) engineer in sweden 20-odd years ago. Frankly I'm a bit surprised that we engineers are so few here. Not over 75% at least.
Anyway, the last 10 years I've run my other hobby and my day job in the blender and ended up design motorcycle mechanics, both chassie and engine, all day long. Fun-fun-fun most of the time, especially at test sessions, but like all jobs it can be a pain from time to time.
Ok, it's got no handle bar, but then again - most racers are allready outa control!
Cheers
