If they were traveling uphill to work you’d think they would gain some of that back coming back downhill. But I’m guessing it might be very hilly terrain where the roads are not level at all. The crazier thing is that their commute is 60+ miles one way (based on saying they are lucky they can charge at work).

I assume they leave work on a full battery after charging there for free, limiting the advantage of regen braking

It's uphill both ways.

GP wouldn't notice effects of uphill and downhill averaging out if he starts at the bottom and charges at the top. And GP is implying he do.

Looking at Tessie, my Model Y's lifetime average is 83% (289 Wh/mi at ~40,000 miles) and my Model 3's average is also 83% (280 Wh/mi at ~53,000 miles).

Most of my driving is in the Washington/PNW, so a bit more hilly and colder than California.

I have 2014 Tesla S and 80-85% is just about right
