There is an option for both sides, now, EU#1 is still limited to 90kph and the rest of the servers to 150kph. Why? Because that reduces the chance of accidents, which then improves gameplay by not having to record, report and fix your truck all the time. I feel 0 need to drive faster than 150kph, and many people will agree with that statement. If you are looking for speed and accidents there are many non-simulator games out there which will fit your need, like GTA V, Watch Dogs 2 and a few more racing games. The clue is in the name of the game, Euro Truck Simulator 2, and American Truck Simulator. You're playing a simulator, so you're reconstructing a job that many truckers in real life do, spent their days out on the roads and you've decided to also do that in this game/simulator. However I have never seen a truck drive any faster than 150kph, or even faster than 120kph. The cars get unstable at a certain speed, so limiting really is not the problem. You'll do your jobs faster than average, but who likes rushing jobs and do as many as you can while you can enjoy your drive and cruise around? This game is not meant for speed, it is meant to deliver loads and enjoy the landscapes while you're driving around a world with many other players or AI. It was never made to drive 150kph+, keep that in mind when writing further messages.
