The breakthrough will come when every place you might stop off on a journey for a meal break has charging points. Motorways are covered by existing infrastructure but away from them, the concept of concentrating fuel sales (including electricity) in one place won’t be needed. Petrol stations receive bulk deliveries of fuel, keep it safe in storage tanks and dispense it. We don’t need it to be that way for electricity.
Doubtless it will happen eventually, but I just don’t think that anyone (including governments or car manufacturers) have really got their heads around the scale of what is required. We live near the M5 motorway which is the main holiday route to Devon & Cornwall etc. On Fridays and Saturdays in the summer, the motorway service stations are all rammed with hundreds and hundreds of cars. In an all electric future, the majority of those cars will be looking to top up during that service station stop. Having 20 or 30 charging points will be woefully insufficient. They will probably need well over 100 as an absolute minimum and, even then, demand will no doubt exceed supply at times. As I say, it will happen eventually but at the rate things are going at present I just can’t see 2030 being even remotely achievable.
