>Once the car throttles down the charging speed, you are probably better off finding another charger an hour or two away - unless you're planning a longer stay.

This is 100% true and, from recent experience, generally a much better way to road trip. Stopping every 150 miles or so breaks up the trip into nice chunks and keeps you fresh.

I took an earlier trip where I had to charge from 10-90% twice due to charger distance and it was much worse.
