In the middle of the 90s, CART raced in the most different and amazing tracks possible. They had superspeedways, street circuits, road courses and short ovals. Now that was a true challenge for cars and drivers, without all the politics and BS that infests F1.
Too bad it's gone, because, honestly speaking, for quite a few years it was the most exciting racing. Now CART is in its deathbed, and we are waiting to see what happens.
F1, obviously, is also a huge challenge, but technology has unfortunately robbed us from part of it.
Oh, and I also have a huge respect for rally. Think about it, driving over rocks, sand and snow, avoiding potholes and having cliffs or trees only a few metres away from you. Takes lots of balls and skills.
Would it be possible, to play forever?
The conclusion reached was that a player is inevitably doomed to lose.
