If you were already concerned by the short distances that electric cars could cover, here is some advice

If you were already concerned about the short distances that electric cars could travel, do not go in either frigid or hot temperatures.
The average EV battery range in AAA’s test was 105 miles at 75 degrees but dropped 57% to just 43 miles at 20 degrees. Heat also sliced the cars' ranges but by not as much: The cars averaged 69 miles per full charge at 95 degrees, 33% less than in 75-degree weather. . . .
If there is a 57% drop between 75 and 20 degrees, what happens if it gets really cold?  I would assume that the distance drops even further.  If the relationship is linear, these first two observations imply a distance of only 20 miles at a temperature of zero.  My guess is that things are even worse than that as the drop off may increase with lower temperatures.

If you notice, the most glowing stories about electric cars usually have come out in the Spring or in Southern climbs.

They're hoping no one asks the "man behind the curtain" question about the possibility of having to use the heater.

Due to 'batteries' means of using a chemical reaction to convert energy, there exists no escape from output variations due to temperature.

Then again, seeing as how automobiles that used batteries as a means of propulsion failed in the market due to the same reasons that exists now, I fail to comprehend why these companies and the government have failed to learn from the failures that occurred the first time. Has one hundred years of history simply been forgotten?

In 1912 Charles Kettering brought the electric automobile starter to market, thereby sealing the fate of the early electrics.

Some things never change...
