> Tesla didn't just throw all the (affordable?) tech they could into their cars

But they did. Since the late 2016 model S, each tesla comes with 1 radar unit, 8 cameras, 12 ultrasonic sensors and a replacable computer system.

At the start, these were not all used, but they have been used for more functions over time.

The model X got the same cameras, and my friend who has one said his car uses the side cameras to prevent the self-opening driver and passenger doors from dinging nearby cars.

They've designed a new faster computer (Hardware 3.0). The folks who paid for full self driving will get one of these swapped in when full self driving features require it.
