Its a bit like phone coverage, in the early days it was based around population and charging is pretty much the same at the moment although you can always use a 3 pin plug. It is getting better all the time though.
North Scotland, North Wales are not good for rapid charging but people do drive EV's around the north of Scotland and 300 miles of range gets you a long way between charges and back to a three pin plug.
If you (i'm speaking generally here, not you personally Quartz) don't like or want an EV then don't buy one, you can have an ICE for many more years yet. Personally I have one and really enjoy it for all that it offers, range is never an issue for me at 70 miles a day but I have done long runs and used Tesla SuC's which charge at mental speeds getting you back on the way in no longer than it takes to visit the loo and grab a coffee. My wife has a Zoe and she loves it, 200 miles of range is plenty for her and we reckon she will own it for many years.
When you do longer journies do you just charge up or do you take a ICE car? That's the one thing I'm always thinking. We often do trips from bath to North Yorkshire that would push the limits a bit for a single charge so I would worry about getting stuck. We do usually stop for a break though
