Vehicle stops at ramp when using wheel collider tutorial

Should I be using different code? I’m using the script and I have everything set up correctly, the vehicle I have drives around quite nicely but the moment it hits something like a ramp it just smashes into it and stops immediately rather than going up it like you’d expect it to at that sort of speed.

Looking around google I noticed people mentioning it could be gravity so I thought about lowering the mass of my car, but of course this means the vehicle is going to fall to pieces.

Edit: I think it might be down to how I’ve set my wheel colliders up, but I’m not 100% sure, another thing I’ve noticed is that there seem to be no changes in the speed of my vehicle when changing the max motor torque? Not even sure that’s the right thing to be changing, looks like I’ve got some reading to do on this type of code.

Hmm, so I saw some stuff about how it might be due to MaxAngularVelocity that you run into vehicle issues, however when I changed it for my vehicle the only thing that really changed a bit was speed and it’s still rather slow.

Okay, to show people the problem I’m having better I’ve uploaded a video showing exactly what happens with my vehicle.
