My brother lives just north of London. A few years ago he drove to Scotland and back in the last gen Leaf with the small battery. Took a few stops and it wouldn't fast change after the first stop because the battery was still too warm. So it took all day. He drove 60k miles in 3 years in that car, it was good as long as you knew it's limitations.
Did the same trip in his new Tesla Y last year. Took three 20 min stops (and arrived with a good amount of charge). Driven at 70mph. No worries.
Last week watched a repeated episode of 5th Gear Recharged, the series where they road tested EVs. In that episode they took a sporty Kia EV just over 1000 miles on the longest continuous highway in Europe, from Oslo to Tromso, to achieve the previous time set by an ICE car of 24 hours continuous driving. Observing the speed limits. One section near Tromso required a ferry. All their stops were planned in advance, using fast chargers. Apparently Norway has the highest concentration of public chargers. Was it 5 times the number per EV that the UK has? I forget.
They still had en route problems, finding chargers at planned stops either in use, or in one case awaiting repair. This caused delays. If they used aircon, the range dropped significantly, so they had to leave it turned off. They only used the available big acceleration once, with big grins for the cameras, and that caused a significant drop in range. It was pretty obvious that they had to drive the EV like a crate of eggs to maximise range. Ahead of them was the camera car which clearly was an ICE. They reached the finish line in Tromso with 1% battery and 4km range remaining and they were nowhere near a charger as far as we could tell. Squeaky bum time. About a minute under 24 hours total journey time, if you believe that.
What is the point of having massive electric horsepower from the battery, if you dare not use the acceleration? Or, if you can't use the aircon when it is sunny? Making that journey in under 24 hours by EV became unlike real-life driving. Perhaps this energy-saving, hypermiling style, is what EV owners often need to do, hoping that on a long journey they will find a fast charger that isn't either occupied or out of service?
I wouldn't like to be an early adopter of an EV motorhome that has a practical range in the real world of maybe 80-100 miles when fully loaded. EVs tugging lightweight caravans might be more useable. For now.
