Fast drivers?

[Kauai]

I have a 70 mile Bay Area round trip along 280. This is up and down hills with traffic in the left lane running 75-85 mph. Occasional short passing bursts at 90, and I use 100 rated miles for the 70 mile trip which suggests you should be fine with a 140 mile commute, unless you plan to go significantly faster. I'll note I have used my car for nearly two years and minimal battery degradation with 20K mile per year.

Sadly, I've already gotten a ticket. I find it hard to keep the car under the 80's, but I see the same 100 rated miles for 70 actual miles with a 320-340 wh/mile. I was expecting better.

I feel the same way about my actual vs. EPA rated mileage in my ICE cars. EPA ratings are contrived driving scenarios that may or may not represent your personal driving.
