Can we all agree on how to drive on the highway?

Right lane: heavy vehicles, driving 5-10mph below speed limit.

Middle lane: cruising at constant speed (at around the speed limit)

Left lane: passing lane only. Can only be there temporarily. Not for cruising. Accelerate, pass, and collapse back to middle lane.

On ramp: increase speed then merge to right lane.

Off ramp: decrease speed then merge from right lane.

None of this should involve any braking. Braking is for coming to halts, not to decelerate on the highway.

Predictability in driving behaviors leads to no unnecessary braking, which leads to no unnecessary traffic jams.
