Is this restless legs?

I thought it was akathisia from my antipsychotics, but I'm starting to think it might be restless legs. It doesn't happen when I'm trying to sleep, which leads me away from the diagnosis. It happens mostly when I drive or am in the car, but also when I'm sitting still for a while. When I'm driving, I'm afraid of getting in an accident because I have to move so much. Is this restless legs or something else?
