May I suggest that at the beginning of games, stop spawning the tanks in front of the APC’s, they just slow, or even stop the APC’s from getting their troops to the battle front, especially since the Tanks are not usually going all the way to the cap point anyway.
Now, in two years my record of having DF listen to any of my suggestions is ZERO, so I already know this one is DOA. 
Added penalties for colliding with friendly vehicles and maliciously blocking the road
it doesn’t matter, the tank will push you out of the road
Tanks need the same spawn delay as planes at the beginning of match. Apcs dont
Nice idea. I dislike how the first point gets instantly cleared by tanks
Some sort of change is definitely needed. I’ve had tankers purposely pushing my APC so it becomes undrivable just to tickle their griefing funny bone. I’ve also been run over on the ground (as infantry) and got killed because of it. There needs to be some spacing between ground troops, APCs, and tanks when spawning into the game.
I had a guy push my APC into a river knocking me off a bridge. Luckily, I was able to drive out but he had stopped between a couple objects and there was a destroyed tank or APC just in front of him off to the right, so backing up was really his only option. I stopped my APC right on his ass pinning him in that location. I didn’t stick around to find out if my payback worked, but if it pissed him off, then it was worth it.
