It's hard to understand that you're playing a simulation game and not a racing game isn't it? Have you ever seen trucks going 110kmh in real life? I haven't,never. The 110kmh limit for my opinion is still too high and on Simulation 1 it should be set at 90kmh.
If you want to race a little more,there is Simulation 2 there you can go up to 150kmh (unrealistic and nosense).
If you want to race like on F1,you have to play on Single Player and playing with mods,that makes your truck engine over powered...
But the question is...what do you find cool about racing with a truck??...I still have a hard time understanding it...did they make trucks that go 90? and 90 they have to go!
This is a SIMULATOR game NOT A RACING GAME!! Is written in the name of the Game and in the name of the Server you join to play...
