yep, in London it's pretty normal to be driving at 30 and be overtaken by a teenager on a scooter with no insurance, no protective equipment and not a care in the world. They can kill themselves for all I care but they can easily kill a pedestrian or cyclist which doesn't seem reasonable to me.

killing themselves is not the worst thing than can happen to them, and not so likely. Other possibilities involve long years of suffering in bed and on a wheelchair.

But the e-bikes are more heavy and will also likely make other people suffer.
