Obviously an Aubergine
The rider taking risks with his own life is one thing - though pity the person who has to scrape him off the road.Only thing that bothers me is how many people are riding around on deathtraps.
I fell out with a customer a long while back because I failed his bike on MOT due to brake discs worn out (to the point you could bend them with your fingers!), why would you even contemplate riding it in that condition.
It's everyone else in his unstoppable flight path
