I am both pleased and curious about the deceleration that occurs when making low speed turns in the Model S. When I approach the turn to my street, I'm going about 40mph down a 3% grade. In any ordinary car, I'd have to do some braking to make the turn. Regen reduces the speed to about 25mph, but then there is substantially more deceleration on turn-in. Could the steering angle be triggering additional regen? Sure feels like it. Or, perhaps it's just a result of the steering geometry. In any event, it's another wonderful feature of driving the Model S and further saves on braking.
