i have to add that on the way home it was raining the entire way amd the mist wake behind the CRX was almost nothing and the rear windows had Zero rain on it.. totally clear.. Signaling its air flow over the car is very efficient..
In the Crx's case the wipers are in a air flow zone, as i was watching rain rdops fly across the winscreen to get a idea of the aerodynamics of the car.. thinking rising the rear of the hood and making a cowl will be beneficial.. and probably lower its air drag even more.
Still cant see how with the fairly boxy front end they get 50 MPG.. we will start where Honda left off
