Top speed of 60MPH; let's halve that for a safety margin, which gives a range of ten miles. There's around thirty towns and cities that close to my home. Reaching any of thirty towns in ten minutes would be far from useless.
If you were a rich person living in (say) a village in the UK 20 minutes is easily enough to fly to the pub, charge it a bit, and fly back.
As a non-rich person it'd be useless to me even if I could afford it (I live near other humans) but I can absolute imagine some people I have met buying one.
