I haven't written anything here for a long time, but what Al wrote a
couple of days ago is really right on. What he says about
liberal-right-wing-left -wing-fake news-etc is absolutely correct. The
best way to convince someone about the usefulness of the metric system
is to gently point out how simple and easy to use it is, and mention
that it is used without a second thought everywhere else on our planet.
Unfortunately, with our miserable political divisions and now the virus,
we on the metric cutting edge are pretty much way out on the back burner
for a while. But it would sure be nice to hear about 2m social
distancing for a change!
On another point, Tesla vehicles have a computer readout showing kWh
used since the last charge, per trip, or overall. There is also a Wh/km
rate display for the same periods. One vehicle I have information on
shows 2200 kWh used for about 15500 km traveled overall. At a $ 0.12
/kWh rate for home electric vehicle charging in northern California
(starts at midnight), the electricity cost is $264 or just $ 0.017/km.
All the driver has to do is select metric instead of miles on a
preferences screen.
