I drive in D on the highway out of laziness. When driving in L, the pedal is very sensitive to foot movements. It gets tiring hold my foot steady for that long. I end up regen'ing when I didn't mean to, and have to accelerate back up to speed. It's just much easier to use D. Of course, when cruise control is an option, it no longer matters whether I'm using L or D. Sadly, the Bolt will regen much more aggressively in D when using cruise control than when not. I would rather allow the car to vary its speed a little than to use 50kW going up a hill only to regen at 20kW going back down the other side.
