The traffic light exploit still works, sort of. They didn't upgrade the sensors or the communication protocol, they just changed it so that it turns all of the lights red. Emergency vehicles can run reds, so it works for them and not you.
- ChuckMcM 11y agoThis is true, and an Arduino and a switchable strobe will let you figure out the frequency. The important thing is to know which direction it lets go first after the light goes away :-) I read an advertisement for a red light camera system that offered this as a feature (traffic management for emergency vehicle (EV) ingress and egress) it had the feature that you had to have red and blue lights, so it wasn't fooled easily by civilians.
- Gracana 11y agoOh, using the same system but taking advantage of the additional signals already present on emergency vehicles... that's pretty clever thinking.
- cguess 11y agoThe article talks about how that actually was not possible when the movie came out in '95, but it is now. Back then most of them were on mechanical timers I believe. They actually quote the researcher that figured out the flaws, apparently in SF the lights are still unpatched.
