What do F1 racers do if they feel the call of nature during the race? Daniel Ricciardo and Max Verstappen answered this question on the Formula One official site, which would have made a different decision under this scenario.
Daniel Ricciardo is not overly sympathetic to the need in the F1 car:
If I have to go to the toilet in the middle of the race, I can easily handle it. I don't imagine doing it during a race when such forces are acting on you. Such things need to be relaxed.
Meanwhile, Max Verstappen thinks a little differently:
Fortunately, this has not happened to me yet, but I imagine no other solution than to just let go.
