Re: practical outside of cities
"I'm not at all sure that an EV would be up to the sort of driving conditions a rugged vehicle like the Subaru takes in its stride"
Is anyone even suggesting this kind of thing?
Choose the right tool for the job. Perhaps from a different range of tools than we have today. But many of them will, at least in the medium term, be very similar. Including the farm vehicles.
"it may seem obvious to you that public transport is not an option"
In the modern UK, public transport doesn't run unless there's a profit (from passengers or from subsidy). Thus much of the country has no useful public transport.
"seven [buses] spanning a 12 hour period on weekdays "
That's about the service my former employers said was acceptable, for shift workers, on a site just outside a big city. No service at all at weekends. The sites they were leaving had buses every few minutes from 6am ish (before early shift started) to after 10pmish when late shift finished, Saturdays and Sundays included.
