It sure seems easy to just say, "Driver better" or "Go Faster"...I found myself stuck on the last two or three. I soon became overwhelmed with frustration at just how good the computer can drive as well as how well they recover after driving into fifteen oncoming cars only to still blow me away.
1. Screw using a Tier 1 car all that means is the computer is going to use the same grade car. After switching through cars begging for the game to just let me finish I notice the computer would down grade if I did. Slower car meant I did not have to be doing 243mph around ten 90 degree turns. I ended up picking up the Shelby maxing it out for one and then the first Audi You get and the computer car changed dramatically...somehow it just made it easier not having to drive so damn fast on the last couple of events depending on the order you have done them.
Truly hope that tip helps a few of ya.
