Not sure about ETS, but in ATS at least, you can disable tickets, weather, random road events, etc. And being skilled with real experience in the real thing, I have done a lot in ATS I would never have dared in the real world. Passing on the shoulder at 95+ with 46,000 lbs pushing the truck faster downhill... OOOWEEE! I've done 106 downhill in the game...
And though I ran safe and legal 99.99% of the time in the real thing, I have seen 117 going downhill in Nevada (with about 2 miles of clear road ahead). Only reason I did it was I was given 2-1/2 days to move 44,000 lbs of food 2000 miles in a truck that would only run 67 mph and barely managed 50 mph uphill (without mountains). Oh, and idiots at the shipper put me an hour behind before I even left, with another idiot at a shop putting me five more hours behind.
I was banned from Steam's ATS forum though. A moderator for the developer decided that I was violating so-called "Global Rules", which Steam themselves do not enforce. Kinda like a Kentucky State Trooper writing you up in Alabama for something that Alabama doesn't consider a crime.
Steam wouldn't intervene, so I told them to stick it where the sun didn't shine, got refunds for games I hadn't yet played, and told them and SCS that I would never deal with either of them again if I could help it. Now, that might keep me from getting good prices on games, and it might keep me from trying certain games, but I don't put up with BS like that. It's the principle of the thing.
