Uh, ok. If 50 is already perfect, what's 58 then?
I wonder where those extra 8 cars came from, because I had the feeling that the cars you could overtake always appeared at roughly the same spots, as if they were only called into existence when you passed a certain point (it would make sense that the game creates them when you pass the checkpoints). If that was the case, I could not imagine how much faster I would have had to go to pass 8 more cars. That's the equivalent of 30 seconds driving. I mean, I was slow in the last 2 sectors or so, because I didn't know the track, but THAT slow?
Got some more track studying to do, it seems.
