I know this is about a year and a half after your post but I was just reading this thread and had to say something. I'm 30 years old. I've been driving either a motorized
scooter or a motorized wheelchair since the age of 5. I first started driving a motorized scooter at age 5 when we discovered it at the abilities expo. It completely changed my life. Before that we used a Maclaren stroller for distances that were too great for me to walk with crutches. For the average child, I probably would not condone renting a motorized scooter to a child. However, for a disabled child who is used to using motorized mobility devices at home and would like to rent one for use in a park, it really is a shame that the age limit to rent a device is 18. Seems pretty absurd to me but that's just my opinion.
