So where are you going? Out into the deep woods? Because most of the places people drive to today are electrified. Remember that I said 'moderately in the future' and 'superchargers are common'. IE even if there's not a charge point now, there will be in the future.
Just driving inland on the eastern side of Australia.The towns are in the range 100km to 150km apart. With the example 30 minutes for 300km range trying to drive that 300km would have the car flat between towns.That is why I said breaks would have to be changed. When I head south 230km would get me to a town with the next town a further 130km. Do the 30 minute charge then the next town to stop at is again 230km as 300km would not get to the next town after that. With the next charge a possible 110km down the road because after that are small towns where petrol stations and motel have been closing and some places are not much more than a pub, a church, grain silo and a couple of houses. Then one more stop after that for charging.
With the initial charge you mentioned and planing for the 30 minute stops it would be doable with stops needing to be more planned than "i want a break lets stop here".
Once down to wanting the 30 min for 300km charges would be stopping in as little as 230km to charge. Starting with a full charge would stop to charge 3 times. Starting with a 30 minute charge would stop to charge 4 times. Making it a 2 day trip instead of 1 day would save 1 charge later in the trip at the cost of a motel room for the night.
It was a round trip of 28km to the local shop for the bottle of vegemite I got the other day. For those trips an electric car with a range of a few hundred km would not think twice.
