When I was racing, I was told to make an effort to get out from behind the car occasionally and you'll be good. Sitting behind it with no effort
to get out from behind and doing it for a long time..he should have been warned first. If he ignored it then he's dq'd on the road.
It's like sticky bottles. Don't hang on for too long.
The medical car is the only place to get a pull unless you have a mechanical and then it's got to be real. Like a derailleur adjustment, or a seat or something.If it's a long deal you pull over.
He rode along behind that car for one reason only. But the call should have been before the kid finished and thought he'd won. But half the UCI folks I've run into don't look like they have ever ridden a bike. They just have a lot of money and want to look cool and be involved.
