It looks like they took out the dip around the telephone poles on the off camber for the upper cats. I guess we hackers tore up too much of the turf.
There's one corner in this video where a lot of people are wiping out taking the inside line. During my race, the spectators were yelling for me to take the inside line (which I didn't). Now I guess I know why they wanted me to.
