Can i push the car to load it on transportation truck ? If not that vehicle is useless.

Yes you have the option like: "secure bimmer". You load the vehicle onto the truck so you are able to transport it.

OK i try all and is no option like that.

maybe a 20 sec tutorial from the someone on youtube would solve all questions.

as far as i know the ferry is bugged.. the truck should work. never tried it myself.

Ok thx.
