On: Tour de France: How professional cycling teams eat...

[WalterBright]

Watching the TdF, I wonder how the cyclists cope with the motorcycle/car right in front of them spewing exhaust in their faces the whole race.

They obviously breathe in exhaust occasionally but the caravan tries to stay far enough that there is no slipstream and the wind would make it a non-issue. Those dunces that light flares during mountain summits are probably much worse.
