60 miles wouldn't even get me to the supermarket and back...

Probably OK for the vast amount of commuters in urban areas though,
even if they can only recharge overnight. Indeed thousands of cars
recharging during the day (when demand is high) is probably not a
good thing.

Compressed air brake regen would have been feasible, and air is
free,
but R&D in supercapacitors and batteries may have pushed air into
the
background for now.

Or even compressed air a "fuel". Saw a demo of a vehicle on the box a
while back but don't know it's range... Or even the use of liquified
air (or nitrogen) as "fuel".

Regen?, Perhaps some use around town for a Taxi but on a Motorway at
around the 70 limit?. Doesn't seem that practical..

Like the new super green bus for London that ran out of diesel when
driving up the motorway...
