As reported by Autosport, Vettel commented after last weekend's race in Spain where he lost places to both Valtteri Bottas and Max Verstappen, finishing fourth in the end. He lost the track position when he went into the pits while VSC was in place.
"It’s the same for everyone but the FIA is supplying us with a system that makes us follow a delta time, and everybody has to slow down by, I think, 40percent, but I think everybody’s aware you can have a faster way to go under VSC than just follow the delta - by saving distance.”
"So, I think we should have a system that hasn’t got this loophole, because it forces us to drive ridiculous lines around the track and everybody’s doing it so I don’t think it’s a secret. Our sport should be in a better shape than supplying software that’s just poor and allows us to find some extra performance that way," expressed Vettel.
Unaware of any such issues, FIA Race Director Charlie Whiting responded that it’s impossible to manipulate the system. Drivers are reminded every 50 metres if they are above or below that reference time.
"I don’t know what he’s talking about, honestly," said Whiting. "The VSC has a map in the ECU which is 30percent slower than a quick lap. Drivers have to follow that lap. It’s measured every 50 metre of travel along the track. It measures where it is relevant to the reference lap and gives you a plus or minus."
