So vehicles already have a turn radius that is constrained by the camera angle. If you rotate the camera with the vehicle turning, you get a tighter angle.
However, with a top-down perspective, since you can’t rotate the camera, the player is confined to turning in within something akin to a cone. Furthermore, if you breach that cone-like shape, your momentum is repelled and your direction is overridden, taking your steering agency away from you. Additionally, it stops the player from being able to drive towards the bottom half of your screen.
It’d be nice to be able to disable this constraint for more vehicle-based experiences.
