I saw something about this in the patch notes, not sure if confirmed.
This mechanic helped filter out LT shitters and made it risky to vault cliffs and stuff. It also made for some fun moments with teammates helping you if you made a mistake.
What is the logic here? It only punished idiots. Yes it sucks getting overturned, yes you become a better driver as a result. Now we will see non-stop LT shittery of the highest order. Thanks WG
