Until Cambridge hires a functioning police department, what's the point? If we compare driver behavior against Cambridge's Professional Sleeping Department's published citation data, it's already legal to go straight on red, do a 360 on red, drive drunk on red, drive in any direction you want on one-way streets, use the sidewalk as a driving surface, park in bike lanes, drive in separated bike lanes, etc etc. If these things were illegal, then we would see some citation data to back it up.

Without a police department, nothing is illegal. In fact, the police have even been driving in the wrong direction on Garden St's new one-way section when they think nobody's watching.

As long as there isn't an obstructed view, turning right on red is perfectly safe as long as you follow the law. But, again, until Cambridge hires a police department, why would anyone bother following the law?
