They take about the same time as with an ICE. I stop and charge for 20m whenever I need a restroom break or some food (every couple hours or so). My car generally goes longer without stopping than I do.
If you're stopping often or long, something is wrong with your setup.
Maybe 50 road trips? Usually hundreds of miles, with the longest at 1000mi. Literally the easiest road trips I've done in my life.
