Both boats and cars are having issues when driving in close proximity to certain objects, such as trees/large boulders.

The big boulders in particular seem to have giant hidden walls around them that cause both boats and cars to suddenly flip or get flung away.

It seems that certain trees cause cars to bounce backwards away from them when they're driven into at low speeds(?)..sometimes.

The clip at 1:45 is simply there to show that the issue doesn't always occur, sometimes it works as intended.

Since it's a fairly long video idk how much of it actually gets watched, but definitely check out the last 40 seconds before clicking off :D
