There is no “reason” for the car to coast either. I love single pedal driving, it is one of the best parts of electric and hybrid vehicles. My only problem with it is a few manufacturers have done a bad job with the amount of jerk from the transition. He is also wrong that the brake lights don’t come on, the ones I have driven definitely do.

You want to coast because it's the most efficient. Regen is better than burning brake pads, but you'll go further by coasting than you will by Regen and then pushing it back out later. Also, the gas pedal doesn't have enough resolution to handle forwards, coasting, and decent braking all one one pedal travel. You have to be super careful to go straight to coast on a 1 pedal driving modem. It's much better to just be able to lift of the go pedal.

> There is no “reason” for the car to coast either. The user wants it to! That's a really great reason for the machine to obey. The driver generally has superior information/ estimates about upcoming conditions and decision-trees which the gearbox does not. For example, "That intersection's red light will probably become green soon, allowing me to efficiently coast for a bit before accelerating again, and I don't (yet) need to brake if instead it stays red." A similar scenario exists for highways, where the driver is managing their following-distance to buffer-away repeated cycles of braking and acceleration. Then there's also the problem of cars where the precise increment on the gas pedal isn't accessible or ergonomically viable, and then coasting serves as a way to moderate the output.

  > The user wants it to! That's a really great reason for the machine to obey. No, the user wants to maintain a speed or slow slightly, that does not demand rolling in neutral. Maybe it is because I have grown up with cars with manual transmissions or maybe it is because I live somewhere with hills and regen is extremely useful, but I don’t find it particularly hard to modulate a vehicle with regen, nor do I think there is an inherent reason for a car to coast other than “it is what I am used to.”
