When I am driving the v3s it happens quiet often that it is like I'm hitting a invisible rock. I can't drive throw that object. It just stops the car an a friend also has this bug at the same places as me. I can't mention the places where it happenes to us, but I will add them if I find a truck again..
Sometimes if there is loot on the road, you can't drive through it. It is just like above.

When you drive the v3s really fast an steer hard it can cause you to flip sideways an the truck will lay on the side. Or it will flip sideways about three times, like it happened to me. I was happy that it landed on the tires again but it is still a bit fearing when driving it.
