The infrastructure is where continued pressure needs to be applied, not the customer.
On this point, you are totally correct.
At the current rate of EV take up and the lack of pace regarding the charging infrastructure, this situation is only going to get a lot worse.
I get one of the advantages of having a bigger battery, is that you have the opportunity to skip chargers that are packed full.
At my local Tesco they have four 7kw Pod Point posts that are free to use for customers.
I can go there any day between Monday to Friday and there is a massive Merc EV parked in the same bay, pulling a charge.
Nobody needs that much shopping surely !.
He / She must work close by and leaves it there all day, every working day.
Monopolising the charger 5 days a week 8 hours a day is a bit much in my book.
At a local new Aldi just around the corner, there is another four A/C posts.
The EV bays are free most of the time because the wall box only provides juice for 1 hour and then stops !.
They have soon got wise to people leaving their cars there all day and buggering off.
Likely not even patronising the shop either !.
