2d1ba4c0649959b1, According to my simple research, they looked at Sims 3 analytics and found people did not utilize cars enough. A majority just used taxis. That was the reasoning behind no cars in Sims 4. I know it may not be what anyone wants to hear, but that was the basic answer. I learned that by reading articles that were dev interviews.
I used cars now and then in Sims 2 but hated them in Sims 3 because my play style usually involves rotating households and due to the game mechanics, I was constantly having to delete cars from my sims' inventories every time I switched to a new household. Not wanting that to happen again is the biggest reason I'm personally not bothered about cars. I wouldn't object if cars functioned more like they did in Sims 2, but at the same time I am happy living without them.
