A major selling point of the cars was the rapid charging. "170 miles in 30 minutes." This was a significant factor in my willingness to buy the car when I did--the ability to make road trips. I was willing to make some compromises, but I wouldn't have bought the car if it couldn't do my most important trips.
I expected some degradation in the battery over time, and factored this into my decision. I bought the car before there was a supercharger within 200 miles of me, and I spent years on the edge of "the great supercharger desert." I intentionally bought the biggest battery they sold for the cross country capability, allowing for some inevitable degradation. I expected the supercharger network to be finished, and its was built out in my area eventually.
It didn't occur to me that charging rate would be cut in half.
Like others, I'd be quite satisfied with a discount on an upgraded battery pack. I expected to need a new battery at some point if I kept the car a long time. Right now though, I've got a car with less than 50K miles, very little degradation in range, but almost useless for travel. My most common car trip is just under 500 miles. I used to be able to do that with about an hour of charging. Now I can't, and my wife refuses to take the Tesla on that trip.
