That's an exceptional use case, though, and it's these which are always wheeled out against electric cars, small cars, anything that makes less mess than the Mustang they have their eye on.
"I can't carry a cement mixer in it."
"I can't drive 400 miles without having to stop for a 2-hour charge"
"I want to be able to sit 19 kids in it"
"I want to be able to drive at 120mph"
<insert other fringe use scenario here>
The truth is that for *most* people, a couple of hundred miles range is fine. And for most of the rest, a couple of hundred miles range is fine for *most* of the time. The trick is finding something to fill out these fringe cases. And usually it's not something you need to *own*.
Also, your mum could drive across Nevada (322 miles) in a Tesla Model S without stopping due to its 300-380 mile range. Although admittedly that's a fringe-case car then.
I bemoan my commute regularly, but I can easily get 40 miles into the range of the crappiest G-Whiz or whatever. And even a "long" drive for me is a couple of hundred miles. Maybe once a year I'll need more range than that, and I don't consider myself exceptional in that regard.
