Codemasters has released a new trailer for its F1 2010 due later this year. The video is based around the dynamic weather system. The video explains how weather will affect your performance over a race weekend, both on and off the track.
Formula 1 test driver Anthony Davidson talks about how the dynamic weather system will work and how it will affect you. He talks about how the NPC drivers will try and seek out puddles on a drying track to cool off tyres; how the water will be displaced as more and more laps are done and many other interesting things, all nifty stuff but I'll let the video tell you the rest.
