Cheaper carbon fibre handlebars

That is correct. It offers a smaller frontal area with hands on hoods and forearms parallel to the ground. However it is more energy intensive without forearm supports.

with the bars higher and a longer reach the hands in drops position can deliver similar frontal area to low bars with hands on hoods.

But slammed bars / stem look faster in the parking lot ... so it must be faster

I tried those bars years ago, the transition part from the round hood bar to the flat bar is very uncomfortable 

I found the same thing. Had them on for one ride and then sold them.

I also thought the question related to comfort, not aero gains.

This old picture of seconds saved over a 48min 40km TT comes to mind. It illustrates how miniscule the aero effect of aero bars would be... 
Of the 17 seconds (0.6%) saved by the frame, what fraction would be thanks to the bars? 

For non elite riders who don't crack a 40K in under 50mins, the aero gains would be even less.

The "aerobars" in the picture is due to the different riding position (forearms parallel to the ground, as mentioned above), and not the profile of the tubing.

Exact numbers would differ, but the principle stands.

Shoe covers and an aero TT helmet = good investments.

and clip on aerobars - ~4% saving for less than R1k

We’ll now we into TT territory and those aren’t allowed in the World Tour Fun Ride Series as hosted by PPA

In case an surprise time trial race happens where you randomly might be at that exact moment in time🤣🤣

Typical Bikehub, a question about Quality of handlebars turned into a discussion (Science lesson) on Aerodynamics. 😎
