The roadster actually does TOO good a job of deflecting wind. You get zero air flow highway cruising, just a little down the back of your neck, nothing in your face or body. I need a small window like they had on cars in the 70's right near the mirror to angle air into the cabin.

"wings".
And thank you for reminding me of my age.

Issue shows up on economy cars as well. My 240sx, celica, and prelude had the similar issue as well. Something about air being heated up by the engine.

Air conditioned air goes through the engine bay through the compressor. Yes, the air comes in from outside, but it has to pass through there. If the compressor and condensor aren't doing anything, it just gets heated by the engine bay and flows into the cabin.

Nissan and Infiniti have the worst HVAC systems I have ever experienced.
If the outside air temp is 60 degrees and you want some nice cool air coming in the cabin and have the system set on vent, the air is still too warm. I have to run the A/C most of the time to keep from feeling like I am suffocating. And it's also retarded that you cannot turn on the recirculate without the A/C coming on. When I am behind a stinking oil burner or smoke bellowing diesel truck and don't want to breathe the fumes I turn on the recirc, I'd like the ability to turn the A/C on or off. I have never had another car with these issues so it seems they need to go back to the drawing board.

all good comments. I've found down here in Texas that the auto climate settings
can be hard to get where you want it. I can set it to auto and on a real hot day
after the cabin cools down most times i have to turn the control knob to 78 or so to get the fan to turn down.. but it still beats baking in your car!!!!!!
