Yeah, cars used to come with ashtrays, and it didn't seem weird at all because so many people used them, for change if not for cigarettes. They were phased out due to lack of demand, and people who smoke in their cars can get an aftermarket accessory pretty easily. But some of the things that automakers thought the public would clamor for just fizzled out because they didn't make any sense even when they were new. Vinyl record players were just a bad idea, was quickly surpassed by cassette and CD players. Pop-up headlights were cool, but only until they quit working, and then it was just another piece of a car that could break and cost a lot of money to fix. It's pretty neat to learn about Landau bars, which survive today to denote that a vehicle is hearse. Some of these features, like ashtrays, weren't really flops; they were just a car part that eventually went away when the world changed.
