Yes, as of 2012 when I could have used such a service. $10 / hour is a fine price for short-term car rental... but since I wanted to use the car to go places, as opposed to just driving around in the parking lot, it worked out to more like $50-100 per hour (of driving).
Bicycle rentals don't work like that -- you get on a bike at one stand and leave it at the stand closest to where you want to end up. I don't know why the car model is so badly broken.
