Gravity/physics manipulation

I want to make it so a vehicle has local gravity, for example so it can ride up against walls, roofs, sticking to the surface without falling down. I have no clue how I would go about doing this, considering I haven’t worked with gravity manipulation/simulated physics before.

My best guess would be making it unaffected, then pulling it downwards towards the surface it’s facing?

That’s exactly what I’m looking for, however this seems to have been created specifically for when not seated, and not to function while in vehicles.

As it says you have to manipulate it yourself

Managed to do this by now. I applied a BodyForce to the vehicle, then used Ray Casting to detect if there is something under the vehicle which decides whether or not to use them.
