In general, watching Netflix or Youtube, is a relaxing way to spend 20 or 30 minutes.
The only issue is when there is no restroom, because some business are not open before 10 am or close at 6 pm or so.
So in this case you need to stop to a gas station or a grocery store who often stay open all the night.
But you might need to make a detour in this case before or after charging.
If you are in a more rural area, you can seach for rest areas
which have in general restrooms.
I recently did an 800 miles trip to go to Yellow Stone National Park and honestly,
to stop every 3 to 4 hours and have a little walk to eat or drink something is very nice in fact.
And after this long trip, I was in fact very relaxed and not tired like I had been in the past with my previous ICE car.
But I should add that I was using the Tesla Auto Pilot so it was more like playing a video game on a computer than driving.
Don't you also share driving with your passenger?
If not, you could drive overnight, so your passenger will be sleeping, and traffic will be less congested.
You didn't mentionned how far you were driving and where?
If you are going from Los Angeles to San Francisco, you only need to charge one or two times.
If you drive cross country, in areas with few Superchargers and amenities around, this will be different,
and it would be advisible to search in advance where to charge and where to eat before doing the trip.
