David. You are not a stupid man. Nor are you a stupid motorcyclist. These things I know.
In both these respects you are not necessarily 'the norm'.
One only has to see the speed demons in shorts and flip-flops as soon as the sun appears. What, did their skin suddenly get leather-like? Eejits in cars with un-belted kids diving around in the back seat is a common sight.
We could take your anti-compulsion stance to include tyres, brakes, lights, horns etc. We could do away with the compulsory MoT test. Let's face it, I know best.
Where one draws the line is down to the individual. Compulsion is needed to protect the stupid from themselves and to protect me and you from the stupid!
