Sure, some people will get hit with the reds. Some people will learn the timing and learn that you can run just one red and then hit all greens, or that it will save you 5+min if you hammer down and pull a "clearly not ok" pass to get around some idiot who's going too slow to make the green timing.

So yeah, you're reducing speeding, number go up, pat yourself on the back. But you're also increasing the incidence of something rarer than speeding, but way worse.

This is the same problem that 4-way stops at roads that don't deserve them create, you're basically teaching people that the signage is bullshit.
