One thing that I forgot to mention, which is extremely important. When getting off of the machine, make sure that the key is in the off position. A few years ago, I crashed my scooter while getting off, because my jacket caught the hand paddles that activate the wheels. I was lucky, because I only hit a garbage barrel, and the machine only tipped over slightly. I was also lucky that there were people around that helped me get up, and get the scooter off of me. I don't know if the newer scooters have a seat switch that disables the movement of the machine when you are not on the seat, and if they don't, they should.
