Car fashion fads

[Miserablegit]

There was a new Stinger GT at the station today and I noticed it had bronze door mirror caps and vent trims - it reminded me of the recent article on the new Seat Cupra wotsit with bronze bits and I wondered if all car stylists holidayed together and that is how we end up with new fads/tat that appear at the same time.

Were Audi the first with the chasing indicators that a few others use now?
