DTM Spa-Francorchamps hosts the German series this weekend. In a virtual press conference at the end of the morning, René Rast keeps his line of thought about the on-track problems encountered at the Nürburgring. "Contacts and retirements are too frequent," said René Rast. "I'm OK with tight racing but I want it to be respectful. What we see is not what the manufacturers, teams and fans want to see. Looking back, my opinion hasn't changed. We will have a general briefing to discuss it. It's clear that five years ago there were 18 cars, not 30, which was easier to manage."
