I am doing now only endurance races and I manage to finish races in top 5 usually. However, there is still people just there to push off other drivers and ruin their races. The consequence is that you cannot basically finish a race without penalties and then your safety does not increase… it would be fair to compute the ratio with respect to the number of laps performed in races. 3 second penalty for an hour long race is rather good (especially when it is a track limit for avoiding a rammer…)
Btw, endurance are great but the bop needs to be revised. There is always a dominant car being 3-4 second faster per lap.
