Interesting, I always thought it was a good idea. Especially if you have ever encountered the same intersections while driving a car at different times of day and notice the different options programmed into the light. For example between 7-9am and 5-7pm there is no blinky yellow left arrow, you only get a dedicated turn signal or you dont. Similarly there are traffic times when a dedicated left turn arrow just isn't needed, you know like the other 20 hours of the day when traffic is significantly less. Thereofre at times you get the blinky yellow arrow along with green for the through traffic. I am all for sharing the road, but remember cars make up 99.9xx% of traffic.

I think the blinky yellow light thing is just ridiculous. It turns a yes or no signal into a maybe. I understand it, but I think a lot of people get confused by it. A constant yellow light was a warning that meant to stop, this siganl is getting ready to turn red. THe system wasn't broke , why do we need to fix it?
A yellow light has always meant the same thing, proceed with caution. It's also not that hard to figure out. Personally I pay more attention to oncoming traffic than the color of the light, your results may vary. If anyone is having trouble with the decision making process regarding when to turn left or not maybe you should only enter nascar races where that decision is made for you.

Or if on your bike, please get off your bike proceed to the light pole push the button and wait for the little emoticon to tell you when it is safe to walk your bike across. Sometimes the little sign switches from a person walking to a count down of numbers, to avoid future conversation when it gets below 10 RUN, RUN FAST.
Carry on.
