Question
What happens when F1 Drivers need to urinate during a race.

Answer
Dear Hudson,
Sorry for my tardy response, have been abroad for a few days.When an F1 driver needs to go, they go (in their car, in their overalls). There is no discreet bottle or compartment to pee in. it very rarely happens that they need to though, as you will see before a race starts, the drivers often rush away for the grid for a last bit of bladder-emptying relief!
