I see people run reds on Jeffrey heading towards Portola direction on a daily basis... Red light runs are most frequent with people turning right from Walnut onto Jeffrey. They don't stop first and look, it seems. I often have to hit my breaks for them.
One guy stops and looks and goes, and then the next 2 people behind him just go not stopping and not looking... I'd like a cop to sit there for a month and ticket as many of them as possible. Instead the cop sits about 300 feet away near the train bridge underpass looking for speeders on the big dip...
