Post here all non technical related topics about Formula One. This includes race results, discussions, testing analysis etc. TV coverage and other personal questions should be in Off topic chat.
Backmarkers are not a problem. They will be there and others will know that. So, they should be able to cope with the situation, particularly in Formula 1.
They could permit extra practice sessions for the three or four cellar dwelling teams to use for testing. Like prequalifying. I don't see backmarkers as a problem though. That's why the regulation limit the number of cars on track.
