This is why the public charging network needs to be 100% better than it is now. We are currently in a perfect storm where EV sales are climbing but the roll out of public charges is glacial by comparison.
You don't need to be an EV sceptic to recognise this. Some of the early adopters, like EVM on You Tube are sounding the alarm with some regularity now.
The government and the motor industry need to make a number of assumptions and plan accordingly.
1) 40% of people will not charge at home - this will be forever. Terraced houses, flats, even some semis (my daughter has a semi with no off road parking).
2) Not all work places will be able to have enough chargers. The guy in charge of these things at my daughter's 6th form college has done scoping studies on this. 40% of staff won't have charging at home and will want to charge at work. They have space for around a dozen chargers - this will entail a rota system with teachers and other staff vacating chargers between lessons so others can charge.
3) 2030 is too ambitious - put it back to 2035 in line with most other countries.
Finally, I don't know what the situation is like in other areas but the 4 big supermarkets near us - Tesco, Sainsburys, Morrisons and Asda don't have a single charger on their large car parks which are rarely full. They either need a kick up the jacksie or some incentive to put some in.
