Agree. I'm hoping that stand on electric scooters will be legalised soon with all that comes with that.
Most importantly standards of safe use. Stand on e-scooter riders should complete the Bikeability training at the very least (if legalised) and hopefully more purposely designed for their safe use.
I can't wait to use one (I have abroad). Brilliant and ideal form of transport in a world that has passed peak oil. Could be revolutionary for people (normally woman) who need to trip-chain (ie lots of different stop offs using different forms of transport).
IMHO stand on e-scooters should be used on the road, wearing a helmet, in the same space that bicycles use. Sometimes that will be a dedicated cycle lane, sometimes that will be using the cycling training I've mentioned above to position yourself safely.
Main thing, as with almost everything, is that the riders should be safe, sensible, responsible and respect other road users especially pedestrians (using the principles of the Highway Code, that with greater power comes greater responsibility)
It's the selfish idiots who are ruining it for the rest of us.
