Regen cannot stop a car. The friction brakes must be used. As the speed approaches zero, so too does the energy that can be recovered via regen. To simulate the same acceleration that is occurring via regen at high speeds (or even to have an appreciable amount), the brakes must be used. All vehicles that have "one pedal driving" are using the friction brakes at low speeds. It's just a physical requirement.
Well, technically, it isn't a requirement. You could stop the car by expending energy (not getting it back), but that would just be asinine.
How exactly is it asinine for the last few mph? I can't imagine it's expending much energy to apply the physical brakes as you would already do yourself.
