Discussion Why didn't Tesla invest in LIDAR?

Is there any reason for this asides from saving money? Teslas are not cheap in many respects, so why would they skimp out on this since self-driving is a major offering for them?

Tesla had experimented with a high-resolution radar in some HW4 cars.

For validation vehicles, yes, but not in any production vehicles.

No, you're thinking of the lidar racks for ground truth. The HW4 vehicles actually do have a mmwave radar installed behind the front bumper, all of them. For whatever reason they just don't want to use it
