The missing point in all the various opinions here is the impact to a driver who, maybe through no fault of their own, has an impact with an silly person on an e-scooter, ends up killing the rider.
Forget the lack of insurance (not required?), lack of need for licence (not required), no requirement for highway code knowledge! Not even a theory test required and if its privately owned is illegal.
Also on top of that, will be calls for incarceration of driver, even if it is no fault, the aftermath and fall out are far reaching, will always be on insurance record, with financial penalties on cost for years do to no claims discount losses.
But, the living the rest of your life knowing you have killed someone, even if you know you have done nothing wrong and they are totally at fault, is a burden you will carry to your grave.
Maybe the law should step back, halt trials, clamp down on the illegal ones, review the need for training, licensing, insurance, sort out the loopholes and complexity surrounding it to protect not only the users, but the other legal, licensed and insured and pedestrians.
This headlong rush to trials is not helping the situation, it is only fueling aggravation towards them, and what could actually be a viable transportation solution is going to become seen as a pariah on our roads.
