Because 280 has many small hills, I first accelerated to 45 miles per hour, entered ev-mode over the top of each hill, and glided down each hill in ev-mode up to 50 miles per hour. I stayed in ev-mode uphill again until my speed dropped to 45 miles per hour, and then i got out of ev-mode and held my speed at 45 miles per hour and repeated.

The mileage was great but I had to use assist about 2-3x more than usual to maintain speed in ev-mode. I also pissed off many people driving behind me in the right lane, but they readily passed me. Battery state of charge remained steadily around 66%. I think if I do this too much, I will shorten the lifespan of the battery, but if it doubles my mileage, then its a tradeoff to think about.
