well in general I'm not a fan of slowmotion videos, so it's quite hard to enthuse me with those.. and yup, it might be hard to put anything else in the first minute, but my idea is that the content of the slowmotion clips could vary a little bit more. maybe you could put a few crashes, unintentional drifts, passes, defending moves etc in it. for me it seemed like you showed close racing, basically lots of cars in a row or on a tiny peace of tarmac - when I was new to lfs, I couldn't get enough of that kind of footage.. I still find it great, but you used too much of it for my taste.
and when it comes to your clips in regular speed (second part of the video), it's imo again lacking of the action-footage that I mentioned
