The physics; water, mud suspension etc..
The random truck spawns
The k700 loader (I like parking my trucks on the paved road on seashore and then grabbing the logs at the kiosk with the k700 and loading the trucks on the road; Coast was always my favorite map due to the loose log/kiosk locations, and seashore is the same way)
The little details (exhaust causing the water to bubble; stuff like that)
I smashed my finger earlier and now it has turned blue and is throbbing with pain as I type this
Running over a tree/bush and it attaches to your axle, basically winching you to the ground and it pulls you backwards (not sure if this is a bug or intentional, but it's very annoying) Was inches away from the objective last night when this happened in a b-131 and it took me like 5+mins to break free since that truck is rather weak and I didn't have any winch points to pull me forward
Camera auto zoom at garages and when entering advanced mode... so very very annoying
Not being able to see the mod before you download it in a lobby. It's not as bad now since there aren't as many mods out, but once you get 50+ pages of mods that take up 10+gigs of space, it's not really feasible to have them all, especially when you are limited on HDD space and download speed. Also too many kids like to use crappy made overpowered trucks that I do not want to use. It would be nice to see the mod before I decide to download
Lack of information in the server list. When all you see is the map name and number of players, it is too easy to keep joining the same lobby over and over... would be nice to see more information such as the lobby leader and hardcore/casual
No hotkey for the cab camera or winch disconnect
The tutorial messages that Tattoo likes. There should be an option to disable these. Cruise and crane control alike. Maybe the cruise ones could disappear after a few seconds like the cab camera ones do. The main thing that bothers me about the crane control ones is how they block the chat
I know I have more dislikes, but it's by far one of my favorite games.
