Every TSLA will have the hardware fitted and on. Only if owner wants to use the feature, she pays upfront, or a little more if activating the feature later. Other than being able to charge a premium for activating later why install it on all the cars? Tesla is basically using data from sensors that'd be in a Fully Autonomous Vehicle, driven by a human for at least a year. Thats a lot of free valuable data being collected for the cost of just the hardware installation! Instead of doing all the testing and tweaking once car is street legal for test runs as an autonomous car, Tesla benefits from putting every single piece of hardware needed for its future as early as possible, just to mine this data gold.
