I want an Active air management system for my SS

when you come to a stop does an umbrella pop out?

it’s only good at highway speeds....in stop and go traffic it will suck... nice but impractical ..

I had an ‘87 Monte Carlo aerocoupe (nascar version) with the sloped rear window....in a literal down pour with rainx on the front windshield going 65 miles an hour.....I didn’t need the wipers and the back window was perfectly dry...raindrops were not even hitting the back window...
