Why no Side Window Deflectors?

Why no mention of Side Window Deflectors?

Just curious why I've not seen any posts about installing these-
Allows you to keep the windows down about an inch to help keep the car cooler when parked in the heat and they will keep the rain out as well (at least on the fronts).
Anyhow, they were my first "mod", bought from here:

Next up will be window tinting, and thirdly I'll probably pick up the VCDS cable. Nothing else planned.
Pritch-

Love the WeatherTech visors on my 2011 Golf. Easy to install in about 5 minutes. Also love the tinted windows. Just follow your area reg's and don't go too dark. In my area of Canada the local police are going around with a Tint-O-Meter gizmo and laying a $110 ticket on anyone who is too dark. It's the law. I went 35 all around.

I'll be having the local Trucks and Moore shop do the tinting- they should be able to tint within the state laws.

I have them on my super duty, but am not sure if they will look good on the P. I wish I could see one in person.
