Depends on the size of the scooter. As one mentioned, the cars are owned by the drivers and not Uber/Lyft and therefore the car my vary. An XL maybe able to fit the scooter, but then the question comes down to who is responsible for taking it apart and loading if that needs done? As an Uber driver, I would not be comfortable doing that. I have transported several disabled persons but never with a scooter. I have taken wheel chairs a few times but those take about every inch if space in my trunk. If you have luggage and a scooter, it maybe advisable to use a handicap accessible taxi, as much as I hate to suggest it, or a shutter.
