Isn't stop and go traffic a kind of battery oriented demand? I suspect it is oriented towards electric useage as a primary power source until it needs the motor to recharge which would mean that it is primarily gas fueled on a long trip with short bursts of all electric for the duration of electric range thereby reducing the gas comsumption and increasing the reported mileage average.

Ideal would be to use electric for any low power demand situation, like steady cruise at 45 MPH or below. ICE is better used for acceleration and higher power demand. The whole idea is that ICE is inefficient at low load situations, while the electric is very efficient.

ICE at low load

AeroStealth put this to the test.
His 2014 Ford F-150 EcoBoost, crew cab, 4X4, with 6.5-foot bed:
22-mpg at a constant 62-mph.
32-mpg at a constant 35-mph.
-------------------------------------------------------------------------------------
The big issue is traffic light synchronization. There isn't any! The transient loads of stop-and-go driving rip an ICE vehicle a new one.
10-speed transmissions are two gears away from CVT economy, but there's only so much one can do.
That's why we have hybrids. BEVs are on the right side of the calculus as well.
ICE won't regen.

Not only due to a real CVT being less complex overall than some transmission with too many physical gears, but also due to hybrid systems often being capable of emulating a CVT, sounded quite predictable for hybrids to become a sensible option under a higher load which CVTs are often claimed to not withstand.

People always tell me that stoplights in Arizona are synchronized for the speed limit.
"Then why do you speed?"
[offended] "I most certainly do not!"
"Yes you do."
"Maybe 5 MPH."
"Five?"
"Okay, 10!"

If they believe that lights are synchronized and they speed then they decide to brake for each and every light?

Dolphins really are the dominant species, right?

Paraphrasing some comedian, "Remember, if the lights are set for 25 they're also set for 50".

Interesting theory. Have you tested this?

Note that it was a comedian. It's beyond my reckoning.

Fwiw, yes it works at 50, 75, 100. Guess how I know? I suppose also at 12 1/2 but I won't go there.

Until they improved it, you could drive the McCaran loop in reno at the posted 50 all day long and never hit a red.
