Like using the heater when its 20 degrees and snowing?
No Thanks.
Like I keep saying: it’s not for all scenarios. Doesn’t mean it’s sh!t. Much of the country doesn’t have norms outside its comfortable operating ranges.
20 degrees and snowing? Drive sensibly and you’ll be fine. He did a number of things wrong contributing to his problems (not the least of which driving a 2011 LEAF instead of a 2014 or later). Helps that you can program it to heat/cool while it’s plugged in before your normal departure time, so it’s already warm when you start the drive, and the battery just has to “top off” the warmth instead of raising the temp 50 degrees outright.
“No thanks” is fine, just stop being rude about it. Works great for a lot of people, but certainly not all.
