On a side note, some people in mobility scooters have never drove a car and it shows. About 6 years ago, I was helping out on produce. Put out some bananas and an elderly lady drove into the back of my legs. Never apologised. Had bruises on front and back of legs.
Then there was a man driving max speed 8mph missing the corner colliding into the wine. He broke about 50 bottles. Do we drive at max when we are going around a corner in our cars? No!
Then some mobility scooters users don’t understand that can’t ride on roads. All of a sudden driving along a road driving a few mph. Cause? Old dear on mobility scooter riding on the road.
A quick correction there.
You can ride class 3 mobility scooter (limited to 4 or 8mph) on the road, but should be aware that you can cause problems, basically don't do it if you can avoid it, but there are times when it's the only option open to the user, especially on narrow pavements, or when some idiot has parked up blocking the pavement*, or there is no safe way to get down from the pavement to the road/back up again where you need to go.
They're also quite highly regulated and must have lighting similar to a car (front/rear/indicators), and the brakes etc must meet a certain standard (even a 20 year old one will stop within about a foot or two from full speed**).
Most mobility scooters, certainly all the smaller common ones are hard limited to 4mph.
They're also typically pretty expensive things, a cheap one is around a grand.
Unfortunately some people who use them don't have a clue, or use them when their eyesight has hit a point where they shouldn't, then there are the normal number of idiots.
Basically mobility scooters are extremely regulated in the UK compared to escooters etc, largely because you can only really buy them through bricks and mortar stores, and they're priced well outside the "toy" range.
*The other option is to try and scrape by the inconsiderately parked car.
**They've got both motor braking, and usually an electromagnetic clamping brake that as soon as you release the controls will clamp down on the drive axel (the brake actively needs power to release).
