Be a Jug, Not a Bottle.
Do you drive on your daily commute? Do you go through a highway toll on your way to and back from work? Are you one of those cars in the picture?
It is terribly frustrating if your daily commute includes driving through a bottleneck.
Bottlenecks are named after the literal shapes of the necks of most glass bottles.
Compare pouring water from a bottle and a jug. Bottles are slower because it would need to stop the water flow to allow air to pass through as it replaces the empty space. The narrow necks slows down the process of pouring water.
