Ok, we've seen both sides of the "wasteful" range question. Let me pose
this: how close to saturation are we for the market of people who can
afford and are willing to have an additional car just so they can buy a
short range (50+ miles) for local driving.
That is, how many people are left who will buy a short range EV with the
justification they also have an ICE car for longer distances?
Let me be sarcastic: under the ideal world I'd have about 10 vehicles:
my bicycle, maybe an e-bike, a small 1 person EV, a small 2 person EV, a
4 door sedan EV, a 4 door sedan ICE, a pickup truck, a van. Lost count,
is that 10? Then, I'd use each vehicle most efficiently.

EV range is interesting as so
many new factors. While long range is nice for those that
actually need 100+ miles/day, most just don't need over
120 miles I see as a sweet spot for most. For
many just a 60 mile range EV can work as many in Fla seniors
only use Golfcarts and NEV's now as their only
transport. And for the few times more is
needed a RE using cleaner fuels or Alum/Zinc-air primary
batteries are already proven to give 1,000 mile range just
EV builders refuse to put in the brackets, plug or space for
them like a trailer hitch mount. We really
need to get these alum/Zinc air RE available as already
proven, just need a market to sell them. Between EV's
and home, building markets if available would be a killer
app. As fairly light 50lb modules could be
sold near anywhere including gas stations just exchanging
the spent one with a reformed one. This is
complicated as EV batteries shrink in weight, space both
which have been improved 30% in the last few yrs and likely
to double range/lb of battery in 3-5
yrs. Next building eff EV's gliders by
cutting weight by 50% with better aero can cut battery
weight, cost/100 miles by 50% even with present EV lithium
batteries. The GM Ultralite, Toyota 1/x,
Solectria Sunrise, Visio.M, and other composite
body/chassis show the way. Sadly the i3
weighs more than a same size steel car from really bad
design using an alum frame instead of just bolting
everything to the CF body. Since it has to pass crash
tests the body has to be strong enough to carry the other
loads anyway. So half the weight, drag
EV's using half the weight EV batteries with 2x's
the capacity even 200 mile range would be low cost,
practical. And in 5 yrs likely to be in
production as by then oil will likely be $5/gal but EV's
need cost no more than a gas car because of these but only
20% to
run.
