Just a short one this, and I'm afraid you'll have to take my word for it since I'm not about to try to get photographic evidence while driving. Earlier today I was driving behind an ancient and badly maintained bucket of bolts that was smoking badly enough to obscure half a battlefield, which in itself doesn't bother me hugely. Windows up and aircon on recirculate and I caught barely a whiff of it. What did annoy me was what else was being obscured by the smoke, which only became visible when I pulled up behind it at some red lights. The rear of the car was covered in every eco-bandwagon sticker you can imagine.
Now on the one hand it's more right on than scrapping a perfectly serviceable vehicle and replacing it with a new hybrid, constructed at greater energy expense than keeping an existing car going. No, that's fine.
But dig your hand in your pocket and do some fucking maintenance, you thoughtless, polluting, anti-social arsehole.
