This really isn't a big issue.
If helmets were made compulsory, I'd continue to ride.
My wife and children would continue to ride.
The world wouldn't end.
If helmets were made compulsory in the middle of a forest and there was no-one there to hear it, would it make a noise?
Endless entertainment is provided for the neutral by the increasingly angry polemic this topic offers us, but it really isn't an issue.
I doubt that helmets will be made compulsory. In the unlikely event that they are, who will enforce the law?
Have a peep at the rear seats of passing cars. How many of the occupants are belted in?
Drive at 30 in a 30-limit area. You will hold up the traffic.
Drive at 40 in a 40... Likewise.
Similarly 50, 60 and 70..... although by then there will be more than one lane so people can pass you.
Have a peep at vanity plates on passing cars.... Many have illegal fonts or spacing. Drivers are either serial repeat offenders or few are being prosecuted.
Everyone can chill. Compulsion won't come - and if it does it won't be policed or enforced.
For what it's worth, I'm against compulsion for any age group.
I'm also strongly against universal suffrage for newts and the banning of pesto sauce on Tuesdays.
