A tantalising look into the future.
I can imagine it now. £30,000 electric car, on a 5 year salary sacrifice/finance scheme. Sat charging for 25 minutes at a motorway service station if I'm lucky (longer if I'm on the M25).
I've just bought a £5.50 coffee and a £1.20 Snickers from the high quality convenience store. I couldn't get into the Shell executive lounge to wait, because I didn't buy it as a £500 extra on my car / from Shell
Finally my 25 minutes is up and I walk back to the car to finish the journey. The charger says "error - connectivity issue".
I move my car to a new charging bay and start the process all over again.
