Re: Because you don't want to accidentally brick a Tesla
There are a couple of reasons this doesn't happen; firstly, the police in this country are woefully under-resourced because $politics, and secondly, if they pursue someone who is not wearing protective gear, such as a helmet, and the rider has an accident, they are on the hook for it. this is exemplified by the relatively recent case of the kids in Cardiff who were going round on e-bikes, got pursued by the cops, and then ended up getting killed; cue riots and a lot of anti-police sentiment, so they really can't do the right thing here.
I believe the unofficial policy, at least around here, is that if the scooter is involved in an accident, or other incident, the police will take it away and destroy, but they won't otherwise pursue the rider. Of course, as well as having their scrote-wagon confiscated, the riders will be done for driving an uninsured vehicle too, because it is not possible to insure these things on the road, due to them being illegal to ride on the road (or pavement). The rental ones you see in many cities have a special license from the government and insurance for use; personally, I think these should go in the crusher too, as they are most often seen begin ridden on pavements, the wrong way up one-way streets, with two or more riders on the, or by school kids, or indeed any combination of the above (like the one I saw a few weeks ago just after school kicking-out-time with 4 kids on it, going down the pavement). They are essentially unpolicable, so in IMHO, should be done away with.
