Missing gills on cars

Today is the first full-ingredient summer day – sun, heat, kids off school, tourists, doors and windows wide, people everywhere outdoors especially patios.  I got back into my sun-baked car after the usual enjoyable session at the Knit'n'Cafe and was driving along with car windows open and setting on cool and fan on – and thought – "What ever happened to side vent windows on cars?'  Gills, so to speak.  The little windows that swivelled so you could direct them directly on a person and get such a refreshing breeze.  Natural air.  Not air that has to be directed to the inside of a car via a noisy fan and then does a rather dusty and inefficient job of cooling.  I suddenly remembered them.  Cut my eyes to where it would be in the car if it was there.  Put up my flat palm in a semblance.  Caused a stranger to suddenly wave back at me.  Put both hands back on the wheel.  Sighed.
