Was that a supercharger or L2 AC? If a supercharger the car needs to do a way better job letting you know the charge after 80% is far, far slower and just not worth it. You'd be way better off doing 2 different charge sessions, both from deeper state of discharge. Your total time would have been less than half. If you're on a multi-stop trip with Tesla's charge curve you're actually better off stopping around 50-60% and heading off to the next charger. I have road tripped my tesla 1000s of km and only once have I ever stayed at a supercharger more than 30 minutes. That was -15C in a snowstorm with a large gap to the next charger and I have the small battery model 3. On 8-9 hour drives I only add about 40 minutes of total charging time. When combined with the necessary bathroom and food breaks the car is pretty much always ready before I am. If it was L2, then the rule is ABC, always be charging. Sometimes you can't avoid hanging around since L2 isn't that fast, but most of the time you should practice pro-active charging and just grab a little juice any time you get the chance. That's harder when you don't have driveway charging, but it's going to get easier and easier as more infrastructure gets built out. All this information needs to be far better presented to drivers, especially ones new to EVs. Gas pumps don't get slower the closer to full you are whereas battery charging varies greatly based on state of charge. There is a learning curve and manufacturers are not doing enough to teach their owners (likely for fear of scaring them away)
