When you primarily charge at home, I'd imagine the need to charge somewhere else most likely to happen after a couple hours of driving, in which case a 15 minute break sounds like a good idea anyway.
We did a road trip like this over spring break. Our last day included 700 miles of driving. Drive for 1.5-2 hours, charge for 12-15 minutes, driver swap, and go. It was easily the best road trip experience of my life. Looking back at the stupid exhausted crap I put myself through in my younger days I can only shake my head.
Same here, also UK. Yes stops at public charging stations are longer than stops at petrol stations, but then I pretty much never "fill up" outside of home. So I have already saved hours and hours that would have been spent on filling up a normal petrol car - if I now have to go and wait 30 minutes at a rapid charger, that's still an overall massive saving compared to an ICE.
