I always wanted a similar system to what you see in racing video games, when they display input controls. A red and green bar on the rear of the vehicle which shows accelerator pedal position, and a red bar which, in real life would have to show deceleration, as a percentage of theoretical maximum, rather than pedal position, as in the games.
I don’t like that it doesn’t give me alternative route options, there are times I want the shortest, not the quickest, or sometimes I want to stick to main roads, and not go through small villages even though I might save 5 minutes. Also, being offline, the routing for a long journey can be cumbersome in my potato phone/aftermarket android car radio.

This is the wrong application, noctua are looking for static pressure, what OP wants is to maximise airflow. Mathias wandel has some pertinent videos on the subject, the ideal is a large fan about a metre or two away from the window, depending on the size of the fan, blowing hot air outside.
