I think it’s better to animate it using code, physics can be heavy on performance and can glitch out.
Looks like front wheel is bumping into obstacles, have set a custom physics material on it? With a 0 restitution and very small friction it should slide over. Another option is to shape collision a bit, like what T-26 Light Tank is using.
Overall, the “obstacle course” in the level is a bit of on extreme side, so far in games that I’ve seen, people have a bit smoother obstacles and landscape.
