My friend lets me borrow his Roadster when he is out of town. We live in an area with lots of rolling hills and long, steep down hill sections of road. When driving down these hills it seems more efficient to coast in Neutral down the hill and much of the way up the next hill. This seems more efficient than using power down hill (regen slows the Tesla too much) and power up the entire next hill.
What do experienced Tesla drivers think? Does Tesla recommend against this type of driving?
