From my experience they get more efficient over 90 mph, I only every go that fast when I have a copilot to help me navigate and help me check lanes before passing. Anytime you let off the accelerator they recharge the battery, its extremely funny to watch the estimated arrival percentage to go up when you are crusing over 100 and occasionally taking your foot off the accelerator. Such a fun driving machine, i just wish Elon wasnt such a cunt.

Is this a serious comment? Teslas are waaaay less efficient over 70 mph. Going 90 mph absolutely destroys your miles/kWh.

Yes, Ive put 100k miles on mine and its just what Ive experienced, it looses alot of efficiency when you go over 55, but ive noticed when I get a buddy (someone going faster in front of me) or I have a copilot watching waze for speed traps, I always gain a few percentage points to my arrival estimate when I drive over 90.

It's called "Pulse glide" it gives more gains with a gas engine but still applies to many systems including HVAC.
