Shock-On-T

Yes, it can be restrictive if your destination is well off the beaten track.However, if you are outside supercharger range, it currently does take way more planning for multi day trips than ICE cars simply because you can safely assume pretty much every town has a petrol station. You cannot assume every hotel has a 22 KW destination charger.
However, this has nothing to do with the 'technology' as you mate says - just getting critical mass so hotels see this as the way to attract customers. That will come. 100 years ago there was not the ubiquity of petrol stations either.
If you are supercharger range, it doesn't matter. It's so quick.
I just think people over-estimate how many road trips they really do, and how much range they really need.
