Re: Only 10%?
How about using emoji for the rating system?
Why? Nobody cares what comes out of their cars exhaust.
Actually, mea culpa, that's not true. I cared when I drove a big Euro 3 diesel. By nursing the engine, keeping revs and turbo boost low most of the time, I could keep the particulate emissions really low. Of course, that meant a soot build up in the exhaust, and a generous well timed acceleration would release it all. Man, I was a hero! I could lay smoke like a destroyer shielding the Grand Fleet! Admiral Beatty would have been proud
And I could put it down where it was needed. Like overtaking a pack of cyclists.
