'Toy Car'

Back in the mid 1970's I had a toy car that was maybe 10" long or so? (Maybe a bit small, maybe a bit larger? I was smaller then so hard to say.) The car was remote control in a way, but not radio remote. It used templates that attached to the bottom of the car. Maybe a figure 8 or a circle. You turned the car on and set it down and it would drive whatever pattern was attached to it. The car was given to me for my birthday and had some issue. My parents said they were taking to the store to be fixed and I never saw it again. I guess they thought I had enough toys. I've always wondered about that car. Does anyone know what this might have been called? Sound familiar to anyone else?
