In a move unprecedented in the Bay Area, the city’s traffic engineers have created a traffic signal with attitude. It senses when a speeder is approaching and metes out swift punishment.
It doesn’t write a ticket. It immediately turns from green to yellow to red.
My take: This will succeed in reducing speeding. By making the decision calculus more uni-dimensional (time vs. time, rather than time vs. speeding ticket), individiuals are more likely to see the folly of driving at unsafe speeds.
But what about civil liberties? One commentator opined: “It’s depriving you of another one of your liberties — going fast”.
Addendum: Tim Worstall writes in:
“The anti speeder traffic light ?
Been around for years.
Here in Portugal they’re all over the place.
And they work very well, just as advertised.”
