I was reading one major issue with lidar is bad weather. Microwave can apparently do that OK but the wavelength is a trade off between accuracy, object size and weather/interference avoidance.

In fairness, bad weather is a big challenge for human drivers as well. Largely because we don't realize how much more difficult it is to drive with limited visibility/traction and don't slow down enough.

Tesla is taking an interesting approach trying to generate a point-cloud based on adding a time-dimension to radar

Visual is one thing, but the ability to react during an emergency is actually even more challenging.
