Nice car
Lots of heated discussions about elec vs petrol, failings of battery technology and so on, but capitalism always finds a way. The simple reality is that petrol is cheap. If you want the electric car idea to fly, gotta make petrol more expensive, and until someone does, there will always be an army of nae-sayers asking "Why the fuck bother?". Once petrol is expensive enough, the cheapest alternative will prevail (so long as law enforcement authorities don't think it'll rip holes in the space-time continuum).
All this green stuff when sold from a financial POV is just nonsense anyway. There are two problems, if there is a saving, then punters will only have more money to spend on foreign holidays, plastic iPhones and so on, cancelling out any benefit. Second, if journeys get cheaper, people will only take more of them. You want to save the environment, the best approach is probably to go kill yourself.
My advice? Stick with the petrol. Use it wisely. When it gets too expensive, find something cheaper, or work from home. I suspect in the days of horse-drawn carts, the early cars were a solution looking for a problem, and the 'leccy cars of today are bit like that. Perhaps sci-fi films are to blame.
But if you insist....
Lead-acid is nasty, but easy to recycle and the charging technology well understood, and we already have the infrastructure for this, a privately-owned car with 30 mile range is the best bet for the shopping/school trip coupled with a community-maintained petrol car pool for the longer ones. Virtually impossible to sell to the modern punter, but it's probably the greenest solution you can have right now.
