I was doing the Blockbuster scenario on Antelope Valley, and for some reason on the second run the car was going so much faster than me and it gave me a scenario failure for not keeping up. I was following the track speed limit, just like I did in the first (test) run, which went fine because the car travelled at that speed that time
Well I tried it again and this time the damn car decided to plod along at 20mph, and suddenly start zooming out of nowhere and nearly left me behind again. Well at least I did it now...
