For the record I'm no longer able to walk or drive a vehicle with pedals.
I live on a remote farming property with multiple fields most of which are not connected to the main property. I designed the house and property with large verandas and pathways to enable me to get around with either a wheelchair or mobility scooter.
I own 3 of the latter, one suitable for off road, one a little faster for longer trips on road, and one inevitably not working. These 3- or 4-wheel devices enable me to have a little Independence to escape being house bound. I managed to get one to hit a blistering 20 kph downhill on one occasion but most are designed to stay under 10kph.
Our street, the nearest village and the highway between, do not have anything resembling a footpath, I ride on the roads when venturing away from the house. Very carefully on the highway.
Here in Isaan there are increasing amounts of electric scooters and devices being used by locals to give them a better quality of life. One local here has a 3 wheeled bicycle fitted with an electric (washing machine?) motor that moves at a good pace. There are many other homemade contraptions chugging around the streets that need to be seen to be believed. None are licensed nor taxed, but all are valuable for the users.
Most road accidents in Thailand occur because of driver error or incapacity, road conditions or speed. The method of propulsion, nor mandated licensing rules, have nothing to do with cause.
There is a selfish army of posters on this forum, most of whom have an American redneck attitude that speed and oil rules the road, who flock to attack the type of vehicle whenever someone stuffs up in an electric vehicle. Very petty!
