Racing: any mode of transportation not raced?

You don’t have to assume any unofficial races. Russia holds an international tank biathlon every year. There are plenty of videos online.

I’m assuming they were distinct funicular lines and not cars connected on the same line (which I think was the joke @Shalmanese was making).

We would have buffer rodeos and yes, buffer races, down the hallways in the barracks. If you sat on one like this guy and leaned slightly to the right (I think), you could more or less get it to go in a straight line with practice.
