80% cap on supercharging stinks to high heavens. In my view they broke their promise of 'free unlimited supercharging' which they made at time of pirchase. I know there are people out there who defend Tesla's action and rationalize their action. But this thing really sucks. No ifs and buts.
It takes away my flexibility for medium range trip greatly. It is going to increase the number of stops I have to make and increase the range anxiety. I use supercharges only once a week when I have a need to do 200 to 300 mile round trips. My car is 75D and has only 237 miles capacity. I am pissed they did this. What is next, I wonder.
