And let's say we do make bathroom stops (kids or whatever); why should the needs of the car dictate when and for how long we stop?

When I was a kid my dad would threaten to leave us behind if we took over 10 minutes dragging out a bathroom stop. I don't see any reason to tolerate a car that takes twice that long to recharge.

On a recent trip I did pull over for a bathroom stop at a gas station. The prices were too high (understandable, only option for many miles) so I didn't buy any gas. In and out, no time lost.

At no time do I want to park in the back of an economically depressed store to sit in my car for 20 minutes watching a crack head defecate in the next parking stall over. If I have time to stop, I want to stop at scenic overlooks and the like.

Look, all I'm saying is when EV charging (or battery swap, or whatever) gets to the turn around time of a gas station I'll be all over it.

Unless I'm dehydrated, no, I generally have to piss more often than every 6 hours, and it's unreasonable to ask a passenger to hold it that long unless they specifically say that can.
