I don't know where is correct topic to ask about this so i decided to ask it here.

I'm currently driving Iveco Hi-Way 550HP and i took a job from "Heavy Cargo Pack" DLC.

And at some speed while driving it looks like cabin interior is kind of shaking, but it doesn't shake a trailer or moving a vehicle from route.

So, is this some BUG or is a normal behavior if truck ?

This is the section to report bugs, and it is already known about. Please do post your game log though, and maybe some screenshots
