> Combine this with accidents (from the bike falling over while stationary, to the rider wiping out, to car crashes) and the useful life of the vehicle is limited. This. I don't see how a bike can be used daily, year-round, for ten years, without falling or being hit by a car driver. And I would never ride again an alloy or carbon bike that has been involved in a crash with a car.
