Stop vehicle from turning to face objects that it collides with?

Apologies in advance if this is a common problem or well known annoyance- I've trawled through the forums but couldn't find anything on it.

I have a simple vehicle that's in the shape of an egg. I've noticed that if the front of the vehicle touches off of another object, then the whole vehicle will instantly turn to face the object which is annoying to say the least... e.g. if you're travelling parallel to a wall and turn towards the wall slightly, as soon as the front contacts the wall, then the whole vehicle will turn to perpendicularly face the wall.

Are there any ways to stop this or deflect the vehicle away? I don't want to change the shape of the vehicle so all I can think of is stopping the vehicle dead if a collision is detected.

Thanks in advance!

there are a few but that just is the way physics are roll a ball agenst a wall what dose it do?

it turns so you would need to place a flat prim under the egg shape to act as a guide to help it to not turn when it taps into a object

Thanks for the suggestion- I tried doing something similar for a different reason when I was making the vehicle but the front edge of the flat prim kept on getting caught on uneven terrain or small ground obstacles- hence the round egg shape now!

I've thought about the physics side of it and it doesn't makes sense to me- if you have a snooker ball travelling at speed and it hits the side of the snooker table at a very small angle, I'm pretty sure it'd either run along the edge of the table or bounce off of it- not turn into to face the edge?... I tried setting everything to glass just in case but it didn’t make any difference

That is because the snooker balls don't have a propellant to keep going forward but use momentum
