Is there really a shoe you can pee on?

Yes, there is indeed a type of setup in off-road racing that allows for the convenience of urinating without leaving the vehicle. This involves using a catheter that fits over the penis like a condom, with a rubber hose attached. The end of the hose is taped to the side of the shoe, allowing urine to exit the hose near the shoe, rather than actually on it. This setup is especially useful for long races where stopping isn't an option 1.

In summary, while there isn't a "shoe you can pee on" per se, there is gear that allows drivers to pee discretely, with a tube directing urine away from the body, typically towards the ground inside the vehicle.
