I can't stand running lights.I'm all for running lights given that I was nearly mowed down a few years ago by someone driving a silver people carrier pulling out of a petrol station in the twilight hours - it was only because I always look back again when starting to cross that I saw hew come flying out with no lights on.
I believe the phrase is "you can have it any colour as long a it's black" as black paint dried quicker than white due to the heat absorption rate.Henry Ford supposedly said that the Model T could only be ordered in black. I don't recall anyone complaining bitterly (whether or not this was an urban myth) about the cruelty of his statement.
Audi does seem to have taken DRL and made it part of the design
Probably in an attempt to make their utterly bland cars stand out from the Passats, Octavias etc which are otherwise virtually identical...it's amazing how everyone thinks Audi is a premium brand, whereas in Germany they would laugh you out of town for such a notion! To my mind, these running lights are only one rung above the purple lights which chavs put around the numberplate or under the car, to make their Corsa/Fiesta/Clio look ever so slightly more interesting, but Audi keep reeling people in...
Air intake is important, but I'm not sure many cars need the huge grilles that we see at the moment.
