> In order to sincerely claim a car has the hardware needed to support a full self-driving capability the car would need several LIDARs, several good quality cameras, a high-precision GPS receiver, and a respectable Inertial Measurement Unit. No, it needs decent cameras with coverage in all directions. That's all what a human needs so that's enough hardware.

Of the vehicles that completed the DARPA Grand Challenge and the DARPA Urban Challenge, how many do you think used LIDAR on their vehicles? I'll tell you: 100%. Out of 11 teams finishing, every single one used LIDAR. And I'll tell you why too: With LIDAR you need much simpler algorithms, and that directly translates into fewer bugs, meaning fewer instances of your vehicle crashing into stationary concrete barriers on clear days.

  It just means your AI is not intelligent enough. The hardware is sufficient, as proven by billions of humans.

Humans use more than eyesight to successfully drive.

  I don't seem to have my LIDAR package installed. Am I defective?

    A well trained neural net doesn't need LIDAR!

This is extremely disingenuous. We have brains (at least, I like to think most of us do) which are capable of many, many times the amount of processing power which currently exists in AP2 and AP2.5 cars. Elon himself has mentioned this delta in processing power on at least one occasion, which is why AP2.5 is even a thing. Simply stating that "humans use eyes to drive, so car can use cameras to drive!" is foolish. (For those who don't know - AP2.5 is the current hardware suite on Tesla's which, among some other smaller upgrades, doubled the processing power of AP2 cars. AP2.5 has two NVIDIA PX2 units as opposed to AP2's one)

I think it's just a matter of writing the correct software. Our brain seems really underpowered to me. And considering what even insects can do with highly limited brainpower, I think the hardware is good enough. All the gains need to come from software now.
