Thus for many it’s a symbolic gesture until the next time something happens which is little different than simply doing nothing until the next incident like say 3 strike laws.
DC recently banned "right on red" but it is routinely ignored and the penalty is apparently a $100 fine. If the penalty was loss of license (maybe not on first offense) I think there's a lot of people ignoring the current rule that would not be willing to ignore the possibility of losing their license.
At least with Arizona, it's the whole state so most drivers won't have the habit.
Of course, if DC just wants to take in a lot of easy $100 tickets, this is exactly the way to do it.
