Mike its partly because you were travelling on a holiday where everyone is out an about. Its a learning experience. Just plan your route using Tesla chargers and their App. The only hickup is city chargers which tend to be very busy. If you install the tesla app, you can see where the chargers are located and how many stalls are available. The othr thing is, it is changing rapidly, as more charge station come online. Its not going to be that bad in the future. Indeed, as petrol pumps are removed to i stall chargers, it will be the ICE cars that will have trouble finding a station in the next 4 years.
I think that you are probably right, and in the future, near or far, EV chargers will become dominant ,as more and more EV’s are sold – it is inevitable.
They say that once you experience an EV, you will never go back to an ICE car, and I think that they are probably right- I , for one, will never go back to an ICE car, and the thousands like me will eventually become Millions and tens of millions!
My next longish journey will be to Goonhavern in Cornwall which is some 240 miles away, so 1 stop will be necessary ( as the car will travel only around 145 miles on the motorway, compared with up to 280-300 miles around Town etc .) somewhere around the Exeter area, where I shall research Tesla Charging before leaving, and we will stay at Fratton where there are Tesla chargers anyway !
