I'm not sure i entirely agree with this. Here's for why:-
I passed bike test, restricted, 6 odd year ago. After 2 year was up, massive sigh of relief. I still hooned with the restrictor. I was 26/27 year old. No car licence at that time. Fair enough then. Had i spent the money, DAS, but i chose not to.
I got a job with the fire service last year that required a full UK licence. It didn't specify 2 wheels or 4 wheels but i met the criteria. Technically. So 9 lessons and the test i got the full entitlement in september last year. GO ME!!!
I now drive a variety of cars for the service as part of my duties (diesels, so 1500cc and more) and if this restriction came into it, i would not be able to do the job. The petition doesn't state age at any point, so if it was only for younger folk, then woop, but otherwise, i'd have been screwed.
And having been riding for years, i'm no road novice and been karting in my spare time since i was 16, had a bunch of driving lessons some years back and i have a fair knowledge of how to handle 4 wheels, even prior to passing my test. I'm only a year in, knocked back down to 6 point probation (which is actually 3 until the SP30 runs out in feb, then back to 6 til next sept) and if this came into force, i'd still be classed as a n00b.
I'm all for equality, but not so much of a fan of whataboutery
