The one unresolved question is: "Is it illegal to time triffic lights in a manner that is out of line with the criteria you set forth?"
I believe many states have a "catchall" for operation of a motor vehicle in an unsafe manner. If I were a cop who was interested in improving traffic safety, and were allowed the time to do such things, I would argue in court that it is unsafe for a person to operate a vehicle in such fashion that the motorist would be unable to handle an unexpected but readily foreseeable occurrence. If I had the proper instruments, I could prove that the motorist would not have been capable of reacting suitably if the light failed to change as expected.
Alternatively, if I could, I'd simply tweak the light so that when I saw such a motorist approaching it would delay the green light by an extra few seconds. Running a yellow light that has just turned red is in some cases inevitable and excusable. Running a light that has been red for many seconds is not excusable except in the rare case that the light has been red so long that it appears to be malfunctioning (e.g. because of a broken sensor).
