Especially IIRC now that electric cars proved themselves too silent, so need artificial sound to simulate current cars. Same with new low noise producing and absorbent road and road surrounding constructions. If you go whole hog, you can change the identification properties from traditional sound images to improved over time.

I’m reminded of the study that addressed whether floor or wall mounted WCs made for easiest room cleaning, and so in the end better cleanliness vs homes, public places but most importantly hospitals. (With an “obvious” answer, which I believe turned out to be correct; wall sets doesn’t only look good, they work well.)

“Don’t shit me”, was roughly the public response.
