Comment: good lord. The lack of logic of some of you is nothing less than amazing. 
1) when you buy a COMPUTER, it has a CPU in it. Some are rated at say 2.0 ghz, and others at 3.0 ghz. These are the EXACT SAME CPU. The difference is that the 3.0 rated was fully tested at 3.0 ghz and work at it. OTOH, the 2.0 was tested at 2.0 and not tested at 3.0. Yet, 99% of them will run at 3.0 JUST FINE. But you paid say $150 for the 2.0 OR you would have paid $500 for the 3.0. What is difference? Just the speed at which they ran the EXACT SAME TEST. 
This is true on YOUR PHONE. On any laptop, etc.  How do you obtain the faster speed? By changing the software. This is just 1 example of this. 

2) Tesla sold you a car with a set amount of charge capabilities. At the same time, they TOLD YOU that at any time, if you want, you can pay extra and the software will upgrade it. So, what do you care if somebody pays for the extra miles / charge? As it is, tesla's profit margins are low on the 60 due to this.
