Not relevant to Howards question really, but should I need a different shopping trolly at the moment it would probably be a second hand I3. (If grid connected vehicle experiments here progress then that may bring the day closer).
The i3 is said to be a hoot to drive. Get a used one with a range extender (aka petrol engine) and you don't have to worry about the shocking state of the charging network.
I've a plug in my garage for overnight charges on the i8 (which shares a lot of powertrain components with the i3, including the batteries)
I try to park & charge whenever I can:
- the on street lamp post chargers aren't yet 'electric only' so are almost always iced
- car park chargers vary hugely, depending on the supplier.
Check what's in the areas you'd drive to using zapmap app, and look at the user comments to see what's working
- motorway charging generally works, if you have the right app: things are moving quite quickly towards app based use, rather than cards.
