A Great video on how to eek out a few more miles from your Battcar. Thrifty Indians give you the good oil.

2/ Use 'chill' mode and avoid fast acceleration
3/ Don't use roof racks, wind drag
4/ Don't carry "unnecessary" passengers, every pound slows you down.
5/ Be anal about tire pressures
A few I thought of.
a/ Find employment up a mountain and live in the valley below so you can coast home to your charger
b/ Move to a temperate climate zone, not too hot or too cold will save range on climate control.
c/ Invest in a power company paying a good dividend, Duke Energy, 3.63% (or go back to 2016 and buy Silver)
Does anyone ever wonder why Tesla's never had thin film solar panels integrated into the horizontal surfaces? Aside from the ascetics, it would be pointless based on how much electricity the batteries consume. 50 to 100+ kWh, even with 1000W of solar it would take 100 hours to charge the bigger one. Or about 12 eight-hour sunlight days. Pointless. The average home solar package is 5000W, at that rate it would take the entire production of a house for 20 hours to recharge from near zero. Two to three days depending on weather and season.
I'll stick with the 98%, I'll go with these

We're 17 years past the peak now and the 3rd World is going hungry and dark. We'll be next, we're well on the way in fact.
