F1 drivers...heck! race drivers in general seriously need to stay away from bicycles....unless they're 'bolted' down in a training room somewhere.
How many is that now?
Webber, Alonso, Zanardi with his special bike-chair, Bob Wollek and now Stroll.
It is a bit nuts to see these guys getting hurt and in Wollek's case...killed....on two wheels, despite going almost 200 mph every weekend in a race car.
