As you are very well aware by now I am all up for mobility and independent living. I use a wheelchair 99% of the time as walking is dangerous, often painful and unproductive.
Today however, I would like to share my solution to an electric wheelchair, which are horribly expensive to buy. This is my 800watt electric quad, which tops out at 40km/h and is perfect for walking my dogs or just getting around my village. They retail at around 2000€ which is vastly cheaper than an electric wheelchair and way more fun than a mobility scooter (max 10km/h). Not sure of the feasibility if you live in a city, but for countryside living its almost indispensable now. It allows you an independent freedom that personally I had lost for years. I am not ready to give up my life and be a full time handicapped person yet, so I allow myself several luxuries to get me though.
