Charging opportunities being somewhat limited at present (Tesla excluded) it makes it more of a planning event attempting a holiday I imagine, so a new learn is needed I guess is the answer.
There are over 44,000 charging points available in the UK, with over 550 added in the last 30 days.
The Mini navigation system shows you a circle denoting your current range, the locations of all charges, indicates whether they are currently free or not, and has a selectable option to route you via the chargers to give the most efficient travel. No need to plan, the car does it for you.
There are an lot of rather outdated myths surrounding EVs which really need to be dispelled.
