the thing about metered ramps
The idea is sound: when there are too many cars on the road, setting ramp entrances to set intervals maintains the flow of traffic. It decomposes in practice (read: “free” market).
Why? (People are stupid, impatient dolts?)
Most are on their way to Very Important Things in their Very Cool Cars texting in their Very Smart Smart Phone. Someone inevitably prematurely accelerates.
Some Guy smarter than most of your family spent weeks away from his, in front of a humming set of circuits. He calculated when the light should stop blinking yellow and how long between each flash of green.
Then boom! some dim hits the wrong pedal or can’t be bothered to wait. The next person (like Pavlov’s mutt) can’t help but jolt forward when faced with the splash of green.
Too many of these renders the meters useless and proves to Some Guy his life is worthless. Which is a shame, because he seems nice.
Similar happens when a lane closes on a freeway. Some Very Important Douche has to wait until the last fifty feet to merge. More do the same and traffic slows to intermittent stops.
Of course, these law-abiding observations come from someone who recently got another speeding ticket and would rather bus an hour than drive twenty minutes. Take them with a grain of salt.
