Why Elon Musk and TESLA will NEVER use LiDAR but they should!

Using LiDAR to get one step closer to fully automated vehicles and how Tesla is trying to accomplish the same goal but going different paths. LiDAR, radar, and sonar all sound so similar they got to have something in common right???? That was my first thought when I first heard about LiDAR. After a quick google search, I found out that LiDAR, radar, and sonar are actually very similar to one another. All 3 of these have the same goal: creating an accurate 3D map of their environments.
