>It can somehow even see stationary vehicles, something I thought wasn't feasible.

Radar seeing stationary objects is trivial, it sees them just like it sees any other. The trick is seeing only the stationary objects which are actually relevant; e.g. not seeing a street sign suspended above the road, or a tree next to the road, but only the stationary objects in the path of the car. The radar configuration that Tesla use[s/d] apparently has awful angular resolution, making this differentiation difficult if not impossible. But this isn't inherent to all radar technology; some radars can have good angular resolution. For instance with SAR or ISAR, you can produce high resolution 2d images. But I don't know what kind of radar systems your Leaf has.

Doesn't it also have to handle things like windy roads and steep angle changes when going uphill? it seems you need both vision and radar to confirm things, eg:

- when on level ground approaching a steep hill, the radar might not know if the object directly in front of the car is just a continuation of the road or not

- when approaching a sharp curve in the road, is the object directly in front of the car actually in its path, or is it just on the side of the road
