At nearly £2 a litre, souls are expensive. 
Easy for you to say from where you're sat.
Factor in the purchase price, and depreciation and time spent charging Vs refuelling I have no qualms about paying £1.65 a litre for petrol in either of my cars that combined including tax and insurance cost less than a deposit on your golf cart regardless of how quick or shiny it is.
I hope you don't get made redundant just before Christmas, but if it happens, you'll be back to a 15/20 year old car before the Turkey is finished because the BMW will be the first thing they will take off you.
There are enough second hand EVs in the market now where over a 2-4yr time horizon (depending on what car you're comparing against) the EV will come out significantly ahead, assuming you could charge at home (which is the majority of the population other than in London).

I appreciate that fuel has gone through the roof lately so EV’s charged at home have the upper hand financially for local’ish runs. They also have the upper hand on a longer run if you are prepared to plan in charging breaks. I’d imagine that it’s not quite so easy for families with toddlers if you’ve got to entertain them for the random 30-60 minutes charging breaks. 
Speaking as someone who does this every few months, the ev really isn't the issue in this scenario. Our iX will do c200 miles on the motorway in the cold (more in nice weather) and adds another c100miles in 20 mins. That's easily 5hrs of UK driving with one 20min stop. By the time that happens, my toddler is done with being in the car and it doesn't matter what's powering it.
We did Telford to Disneyland Paris over the summer which is 4.5hrs driving in the UK, 3hrs in France plus the train, plus any rest stops, arguably about as long as any one-day family road trip in the UK. We had one longer stop on the UK side and one short stop on the French side. We did fuel up in the Eurotunnel car park but could easily have carried on without. Then on the way back one stop in France, 2 in the UK - this is exactly how we did it in the Galaxy diesel (toddler more tired and more grumpy -> more stops).
Did the car make any difference? No, she was still grumpy AF after 4hrs in her car seat!

If you're one of these people that likes to do 4-500miles at a stretch, then an EV wouldn't suit, but for more typical driving patterns I can't see them being an issue, especially for families who are stopping anyway.
