I'm glad you posted about the tires. Supposedly the most important technological advancements in the past few decades for motorsport has been the tires. It's too bad that F1 is no longer advancing the development of tires.
I know the title of this thread is old vs new, but the point is really so I get know all the little details of F1. I generally hear it referred to as being the fastest form of car racing. I find it hard to be a big fan of most professional racing leagues, but I do watch on occasion. I remember in the days of GT4, and it must have been in like 2005... When I watched a race when Schumacher was winning all the time. In this race I saw him battle it out from like last place to first place. He actually tail braked into corners with a puff or two of smoke coming off one front tire. He passed people practically drifting in an F1. It was really cool to me since all I knew of F1 was the GT4 F1 car in the game, and that one was incredibly fast. I tried to drive the GT4 F1 in the same way and got pretty good, eventually. Every F1 race I've watched since then hasn't been as exciting... But it's still alright.
I do enjoy RallyCross all the time, no matter what, though.
