To be honest - I'm not sure why the loophole should be closed. there are lots of people that could benefit from them despite not being registered disabled. For example my dad has really bad knees and sometimes can't walk to the end of the street - let alone the shops - and he isn't registered disabled. he doesn't have a mob scooter though.Not currently. Pretty certain anyone can buy and use one although I believe this loop hole is due to be closed. There are a few around where I live who are using them as cheap short distance motor vehicles as when they arrive at shops they seem to have no problem hopping of and going around the shops shopping
Much better idea to use one of these for short trips than an expensive, polluting motor car. In fact, I'd love to see lots of small electric personal mobility devices to replace short journeys in cars - i.e. small fold up 10mph electric scooters with 5 mile ranges would transform transportation in our major cities.
