How many times?

[Martin Cassini]

How often do you approach a green light, as I did on my bike just now, only for it to change to red before you reach it? Meanwhile the poor suckers on the other road have been waiting while no-one was using the green. The controllers tell us they have ITS (intelligent traffic systems) which can sense demand. No, the most intelligent system is the human ability to negotiate movement and to make subtle adjustments in the blink of an eye - something your control systems can never match. Meanwhile, taxpayers’ billions continue to fund systems that do us no good - down to vested interests and ingrained dogma, presumably.
