Yes, I have one. It’s customary. Nothing ostentatious, typically a small AWD SUV of some kind. Current one is a Subaru Forester. It’s informally implied/understood that it should be used only for business-related driving.

I work for a large company that still has a car as part of compensation package. I’ve not heard of this elsewhere. Anyone else drive a company car? Fwiw, no driving is required for my job and I take public transit to and from work. My car is much maligned on the other thread, and among my friends, but I didn’t choose it.
