Driving stick, I would do this all the time. In fact, I’d do it in the left lane, which I would never do, but for the fact all of the lanes are just constant stop and go. I’d leave massive buffers, 20-30 cars, and just cruise 5-10mph, and never stop. I just don’t understand why anyone wants to use their brakes at all, I hate using my brakes. I’d rather just coast in perpetuity than feel inertia in any direction.
