I'm still waiting to hear how the government plans to solve this or incentivize private investment for this setup to work. Because yeah, if you live in UK and don't have a private drive then I have no idea how you're using an electric car, unless you literally have a Tesla and live right next to a supercharger(I know one person with that setup and it works fine for them, it's literally one 20 minute stop a week and they get enough charge to last them a week).
>>Most of my miles are done on long journeys.
Funnily enough, for that use case you should be ok-ish, as most motorway stops in the UK are now equipped with rapid chargers, so if you're just driving up and down the country you should be able to just charge when you stop for a break, and with modern EVs easily doing 200+ miles per charge this really shouldn't be an issue.
The other thing is - you are an outlier if most of your driving is done on long journeys. Most people use their car to do a school run and commute to work, usually no more than 30-50 miles a day. If that's your setup(and you can charge at home), then EVs(and PHEVs to a large extent) are just a no brainer.
