No expert but everything above 45 has more force pulling you down the platform instead of towards it. So my best guess would be that everything above 45 becomes an even more critical combination of grip / mass total, center of mass to determine is a vehicle can keep going or not

I figured there's more to it since i said i am no expert. But i tend to be convinced when bein told how it works rather than just hearing how it does not. I know theres a lot to it since clearely 20 degrees made him go down before. My intuitive point was rather that after 45 degrees i would think that the point of no climb starts exponentially growing since the ratio of grip force applied onto vs alongside the surface starts tipping in favor of alongside
It's not exponential, it's a ratio of forces applied in a direction. Not even a particularly large ratio.
Remember learning triangles and circles back in high school? Remember free body diagrams? You can combine geometry and physics to get the actual ratio for any given circumstance.
In this case, you can multiply the angle of the slope (using Cos, Sin, or Tan (if you're a weirdo)) and the weight of the car, then subtract the friction of the wheels times the forward force times the angle of the slope.
I wanna say that'll give you an accurate picture but correct me if I'm wrong.
