A highway has two lanes to provide more room for folks who drive their cars like boats. It provides you with freedom of choice: to choose a lane, irrespective of speed, that suits you, that enables you to coast alongside your buddy at a stately 40km/h, while you're on the phone with your other buddy. And should you notice a fast-moving vehicle approaching you from the rear, it is your god-given right to maintain your course and not yield to the scurrilous pursuer, who may or may not be racing to resolve a life-threatening situation.
It has been said that an Englishman will form an orderly queue of one. A Bajan, on the other hand, will form a large queue... as long as they are at the front of it.
