'close' is subjective. My wife used to stop for petrol when the gauge reached mid-level, although she now isn't ruffled by our LEAF reaching home at 20% SoC. Experience helps a lot, as does the remarkably accurate and helpful range tools that Tesla offers. We have owned our Tesla for about a year and the range estimate for trips has been off at most by 2% SoC. Crazy accurate, in part due to the car taking elevation changes into account. You have to see it to believe it.

In any case, 14% SoC in the Model 3 LR is about 44 EPA miles. That is not much less than our LEAF charged up to our usual 80% SoC.

It REALLY matters what that 14% is of. On my old 24kWh Leaf getting under 20% was stressful but 14% of a 100kWh battery is not something to worry about.

On my new Leaf I have no issues until I get to 10% which is pretty much the same as 20% in the old leaf.

I always found the usage of percentages to be misleading. I would much rather be told how many kWh I have left. In sagebrush's case he had 14kW which translates to some 70 miles or so.

No, it wouldn't matter much to people like my housemate. They don't see the number of miles left - they see a low battery.

This I have seen/heard many times. People still haven't completely wrapped their head around the fact that they have a refueling station in their garage. This is why LEAF Spy is singularly valued as a range extender. I might be different in that I don't care if I get home with only 30 feet of range to spare (I have come close to that many times!) because it is realistically 29 feet more than I needed!

But other people don't see it that way. I think part of it is the "gotta have enough to get home AND to a gas station" ideology.

Not in my wife's case, anyway.

Her habit with an ICE car was to mostly ignore the fuel gauge, so on the occasions when she did look at it a reading below half prompted anxiety. Her habits with her LEAF are simply different: she either plugs in at home regardless of the SoC or she looks at the battery SoC before she leaves the car.

She adapted, even though flexibility is not her strong suit.

My HM adapted by getting a PHEV. She now drives an EV in town and a 65+MPG hybrid on longer errands. (She is pretty religious about plugging in three hours before leaving.)

That is better than 98% of car owners so give her a brownie !

My wife was unhappy about losing her Toyota Prime for a LEAF for many of the same reasons your HM has but when faced with a done deed she adapted quickly. Nowadays she hates ICE vehicles almost as much as me :D

Compared to what this Norway test shows, the 62kWh battery does substantially better at temp mgmt and charge rate at temp.

Still a substantial drawback on a hot day. Once the battery was at 120 F the charge rate was reduced by about half. The exterior temps were around 100-105 F.
