Most of the planned “vehicle nerfs” will only seriously effect the default vehicles like the default cars, trucks etc, because they won’t be off-road capable, or tough enough to ram monsters with impuny, or large enough to push aside other vehicles clogging the road.
The problem we’re trying to address isn’t “players are too successful when they have a vehicle”, it’s “vehicles are unrealisticly tough and powerful”. Again, that’s the default vehicles…
If you go to all the trouble to make a ginormous deathmobile, we aren’t going to get into an arms race with you. Other than other buildings, trees, etc, yea it’s just a matter of how big to make the vehicle in order to smash your target. Even with vehicle hulks, it should be doable to make a deathmobile that can shove them aside without being itself destroyed. If you put in the time to make something like that, you’ve earned your rampage.
