Re: Chicken and egg...
Not suitable for everyone but most EV owners have the most convenient place possible to charge them - at home. Once the councils get their act together on roadside charging options (some already are) then public charging for the odd few times a year it is needed will be more than enough.
Once reliability gets sorted out along with being able to pay with debit card then there would be enough public chargers in the UK at the moment for the needs of EV drivers for the next few years. There is massive investment into public charging without their being a big tipping point for EVs. Every petrol station will also get in on the act once their fuel sales drop - BP and Shell already have started the process of adding supercharging.
