@mohammadali118, nobody knows for certain yet. Most of us here at Answers HQ are volunteers. And while there are some EA employees who read these posts and sometimes answer, they might not even know yet if there will ever be cars in TS4. 🤨
Cars are a huge problem not only because we can't drive them very far (like you mentioned), but also there are some neighborhoods that don't even have roads at all, like Forgotten Hollow from The Vampires GP! 😮 Other neighborhoods were also designed without driveways, which will make houses that came with the game (like the Goth's house, the Pancake's house, or the Landgraab's house) very difficult to redesign in order to include driveways and still have the lots look nice. Many houses that are pre-existing in the game will have to sacrifice yard/landscaping in order to make this work! 😞 With bicycles, you don't have to worry about driveways and making a lot of room, so that is probably why they were easier for EA to implement, and easier for players to store on their lots! 😉
Still, it is possible. Cars would probably have the functionality of the cars that TS2 had, where you could park them in a garage or driveway, drive them off the driveway, and down the street before they would disappear. You would also probably be able to sit in your car and listen to the radio, and of course your Sims would most likely be able to woohoo in cars! 😃 And if we do get cars I hope we have the ability to buy an old junker for cheap and then refurbish it and sell it for a nice profit like we did in both TS2 and TS3. In TS2 doing this was a great investment!
However, I fear that even if they add cars like they did in TS2, many people won't like it since many people will think that having cars will mean that we get open worlds in TS4 😞 , which EA has already said the TS4 engine isn't built for open worlds, so we will not be getting an open world at all. I would be satisfied with having TS2-stlye cars, but for those who think it will mean an open world, I think they will be angry and disappointed.😢 So I hope I'm wrong and if we get TS2 - style cars in TS4, I hope people will still be somewhat satisfied! 🤞
