You think "GREEN" circuit race for nos is hard. Wait til u get further in. Trying doing those speed runs later. 1 crash or hard break and it's over you will never hit 120-140mph.
I do agree the starter races are not fair at all. I'm sure they don't have NOS either but they should at least attempt to do some sort of class for cars like NFS: World. Trying to beat AI whose car tops out at 130-150, while you are stuck at 120 is not fair. Not to mention their insane acceleration. I mean you shouldn't be verusing lambos and corvettes at 'green' events with fords and chevies.
