Just be glad you don't drive an old Civic CVCC..... the original '75s (if they had the optional dealer installed A/C) would disengage the compressor clutch at idle to save gas...... that's right, when you're at a red light, you have no air. I know someone who had one. He got smart, though. At a long stop, he'd keep just enough gas on it to keep the A/C going.
