I've done 4 3000km road trips and intentionally took the EV leaving the ICE vehicle at home. It's a better car, and we need to stop to bathroom anyways, so charging isn't inconvenient. Saving a few hundred dollars in fuel is nice, too.
You probably wouldn't for a 450mi trip, so long as you're driving an EV that's even halfway decent for road trips.
2. unless you have an old or low mileage battery you won’t have to stop more than once
3. if you do stop twice (which you should) you should not need more than 15-20 minute stop
My back and butt beg me to stop every couple hundred miles anyway, so on a long road trip I plan for a lunch stop. Longer than 450 and I stop for the night or fly. But I don’t love road tripping no matter how big the has tank.
Another other example that I couldn't make work was multi day stay in Gardiner to visit Yellowstone National Park.
Third example where I struggled was a weekend trip to Lincoln City, OR. No usable chargers within the city or along the coast. The ones listed on maps have restrictions. The only way was to get a full charge at the last station on the way there and keep careful watch over the remaining range while there.
ICEs have access to a much denser network of gas stations, which eliminates range concerns. EVs aren't there yet and the additional trip preplanning imposed by that is real effort at times.
