> In my ICE, its wasting tons of gas sitting there idling... This was surprising to me, Tech Ingredients tested the fuel consumption of idling ICE vehicles and found them to be incredibly efficient while idling. https://www.youtube.com/watch?v=kNiapuA0yTQ For example you'd waste more gas dropping your kid off at practice, driving home, and returning to pick them up then if you just sat idling in the parking lot waiting for an hour. FWIW, I own 2 EVs and seeing people idling in their ICE vehicles still annoys me. |

Its not really that they're incredibly efficient, its that the energy needed to move you home and back again overall is massively more than what you'd use idling. Its still a very inefficient use of energy, from the perspective of the amount of energy in the gasoline being burned versus the actual useful work you got out of it in the end.
In that video the 2012 Mazda 3 used $1.53 in energy cost to do pretty much nothing at all. There was some snow on the ground but it was otherwise sunny, so I doubt it really needed to try and heat that much but I don't really know the air temp. That pickup used $4.10 in energy cost to once again also do practically nothing. The Outback used $2.95.
My EV has a 68kWh useful battery pack. Idling for two hours in extreme heat might use 10%, but I doubt that. I'll regularly precondition for 15-30 minutes when its hot outside to bring it down to temp (way more work bring it down from 100 than keeping it 70) and it normally only eats a few percent of the battery, but we'll err on the high side it'll be fine. I pay ~$0.10/kWh. 68 * 10% * $0.10 = $0.068. And even then, if it was a decent-ish day outside (sunny, not cold wind or extreme heat, probably like in the video) my EV would have used probably less than 2% keeping the stereo and DRLs on for a couple of hours.
My EV is pretty similar to that Outback. So for about the same idling that Outback would cost almost $3 while my EV would cost less than $0.10.
