Matchbox cars were the best!
In particular, they tended to roll much better than Hot Wheels.
The "axles" were some kind of fine spring steel. The matchbox cars had noticeably less drag than other brands and rolled farther and more straight. The plastic on the wheels was more flexible and smooth.
I do think that some thought went into how these things rolled. Or maybe I am mis-remembering my childhood experiences? I guess I will never find out!
