I've been seeing grey primer-ish cars for years. But, yes, more recently almost seems to be the top choice for new cars. Can't for the life of me understand why anyone would choose such shades.
It is not that distinguished grey some very much older cars used.
Have been walking in town, and other areas with traffic recently. And, due to the strong sun, have been wearing my sunglasses. That sort of dead grey, combined with no daylight driving lights, makes them actually difficult to see. Not as seeing if you stare straight at them. But that noticing them in your non-central vision, against grey roads, and with them on the shaded side of the road, means they are too easy to miss.
