These battery operated toys were made in the early 70s and all shared the same idea:
a car with a brain!
Many very different approaches were used to let toy cars drive in a preset driving pattern. And make it drive a rectangle, oval, zig-zag or even a figure 8.
Toy companies like Hasbro, Eldon, Entex, Bandai and Radio Shack made around 30 different cars and trucks, most of them made in Japan or Hong Kong.
