The car clearly lacks enough sensors to become truly self driving. How is it going to avoid changing lane in front of a faster moving car, when it has no rear facing sensor with longer range than 12 ft? How is it going to tell the difference between a pole and a child on a bicycle before doing a right turn, when it only has simple sonar sensors in that direction?
They could at the very least have added more cameras. Cameras are cheap. Why not let the computer have 360 degree view of what is happening around the car?
But it might also be that there is no way around using LIDAR. It is expensive like hell, but that might change when you need millions of devices a year.
In any case, the new Tesla does not have the hardware necessary to implement the vision of a self driving car. They know it, so that is why they call it "auto pilot" instead. It is just sad that it is nothing new. Every other car in that segment already has this "auto pilot" under different names.
