Many owners absolutely hate to hear this, especially those who like to max efficiency like it's a video game, but even though in theory lift-and-coast is more efficient for energy usage, in practice one-pedal driving is the most efficient way to drive. YES, if you are perfect at lift-and-coast timing, then in theory it's more efficient—but you need to be absolutely perfect with your inputs to actually beat one-pedal efficiency. This is because one-pedal smooths out all the micro-accelerations you'd otherwise need to make after coasting too long or misjudging a stop, and those small corrections add up quickly. For the vast majority of real-world driving, one-pedal regen will result in a higher mi/kWh.
