    If Lidar becomes affordable Tesla will have no other choice but to use it

    I think it entirely depends on how cheap it gets relative to radar. For example, if for the same price Tesla can get 360 degree surround radar, I'm pretty sure Tesla would rather spend the money on that. Note that even in this case lidar would have gotten well into the affordable range.

    Lidar is usually paired with radar.

    Radar is very low resolution and (from my understanding at least) only works with metallic objects. I can't see how that would make self driving feasible, even if it's 360 degrees. Would work in an airplane though.

    Just like how lidar isn't standing still, radar is also constantly improving. The 77Ghz band currently used is already as step up from previous 24 Ghz band. The next step is a 79 Ghz band which would be good enough to detect a person even as they are opening a car door to enter.

    Radar definitely does not only work with metallic objects. People also return a radar signature which allows it to be used in pedestrian detection:
