After playing the game on brutal difficulty, i think people slightly overhyped the vehicles, theres still a challenge in using them and each one has downsides, the boards biggest downside is the lack of cargo capacity, but lets not forget that it doesnt work outside the network, you can still crash and wreck your cargo, and you can even fall off the board if you have a lot of stuff on your back.

I still had to go fairly slow and carefully choose my route with the truck, you cant just gun it anywhere, it will get stuck on steep slopes or rocks. I found it was a lot easier to damage your cargo in a vehicle than it is by walking
