Re: Pedestrians aren't the only ones who matter.
When I asked you to explain you stated when the signals are resynchronized to the lower speed, the average speed would not be lowered when the speed limit is lowered.
So if the speed limit is synchronized and the speed limit is 30 mph and assuming the road is not overloaded and you can get all (or most of) the green lights and your origin is the beginning of the street and destination is the end of the street, your average speed would be very close to 30 mph like 28 mph.
Now when you lower the limit to 25 mph, cars have to travel a little slower so you decrease capacity and fewer cars can get through on each signal so the traffic has to move slower given volume stays the same. (You would probably miss an additional light.) Your average speed is now reduced from about 28 mph to about 21 mph.
THEREFORE EVEN UNDER THOSE OPTIMAL CONDITIONS, YOUR AVERAGE SPEED IS STILL LOWER WHEN YOU LOWER THE SPEED LIMIT.
The only situations where lowering the speed limit does not effect the average speed is (1) if there is so much traffic that you cannot travel at the speed limit anyway and (2) no one is abiding by the new lower speed limit anyway.
It is obvious that those two situations were taken out of the equation from the beginning and please don't tell me they weren't even if I didn't specifically mention it. IT WAS ASSUMED, just like No stopping on highways does not mean you should hit the car in front of you when it comes to a stop on the highway because of traffic.
So discounting those two possibilities, there are no circumstances where lowering the speed limit doesn't lower the average speed. EVEN THE EXAMPLE YOU CITED.
Will you admit you are wrong now? Of course not. I wouldn't expect you to.
