Reading in the Owner's Manual did not enlighten me much on Sport Mode. One YouTube video and two comments here in the Forum lead me to believe that it "just" changes the "sensitivity" of the accelerator pedal (i.e. less foot travel/less angular pedal movement for the same increase in power). Are there any other changes? Does it lessen "regen" while coasting, braking, or "paddle-pulling"? Is it like the opposite of "L" mode? I think I read that it DOES use up battery capacity faster. Other than "fun", does it serve any other purpose? "But officer, I just had it in 'sport mode' and did not realize it would make me exceed the speed limit!"
