Hacking the system to get green lights the whole way in this area is a lot easier. They all use motion sensors programmed to green light for vehicles with strobes flashing at a given frequency, which just so happens to line up with the flashing lights of all the emergency vehicles around here (which, I take it, is the intention in the system). With a little practice you can flash your headlights at the right interval four or five times about a half or 3/4 block before you get to the intersection to get a green light every time.
Just don't let the cops catch you doing it. Not only is the fine absurdly large ($600 for each light they catch you flashing) but they really don't like it when people screw with a system meant to keep everyone safe.
A friend of mine got nailed for this to the tune of $2400 and a night in jail. Incidentally I was sitting in the passenger seat at the time and trying very hard to convince the cop I didn't know the driver, or at least didn't want to, after the phrase 'stupid pig' was uttered.
