it’s not just you. I actually set out to test this out twice and yeah it cannot destroy vehicles by ramming into it with boost. This makes the Chopper less reliable than the Ghost since it’s now just a ghost that can only drive forward.
Cool, but unfortunately very rare to happen because they removed the extra damage it does to vehicles. So it could have been a ghost/warthog you hit it with seeing they do the same amount of damage.
On topic; the chopper seems to be a decent defensive (suppressive) vehicle or to take down hogs, but not great against infantry. I hope they add back the ramming damage
