both concerns are absurd. wash your car, use your heated seats, you paid good money to do both so do them without crapping yourself.

as for the hard water concern, if you dry your car you don't need to worry about hard water, if you love to let the water bead and dry in the sun then you're not the sharpest tool in the shed anyways so water spots are well deserved...in short, dry your car, use your heated seats, kill all those stupid RSX's that try to race you! is it just me or does every god dam RSX in the world want to give us a go....i've killed at least 12 since i've gotten the car.
