I think that by adding more generic NON ACCESABLE cars seen in traffic. Stuff like the new AI delivery robot, which people truly don't missout on (as a drivable vehicle) and helps make the world more immersive, having a revelant, cool side vehicle that stands out in traffic due to it's excuslivity to being seen in traffic. My idea is that the devs could quickly model traffic-exclusive vehicles that are not unique vehicles. These cars would be simplified and very generic, making us feel that we're not fully missing out on cool cars. The simplified traffic cars would be random lore-friendly cars with generic designs, such as a random Stellantis SUV badged as a Bruckell or hatchback badged as an Ibishu. Seeing these cars in traffic would make the traffic more realistic, interesting, along with expanding the brand's vehicles. All these benefits are topped by the fact that (I assume) modeling and implementing generic, random, boring passenger cars would be incredibly easy due to the simplicity of creating simple traffic and the rather generic, non-creativily extravaggent designs of these cars. Though it would be sad to not access these vehicles as standalone cars, it would be a small gesture which players would understand is solely limited to AI traffic, which stands to benefit. Adding these cars would be easy, expanding both brand and traffic diversity, making the game's traffic more interesting and brands more fleshed out.
I feel like first the devs need to add the remaining base game, like the SBR, Hopper, the new car, and MD
I wonder if the new delivery vehicle was a test for this idea - it would make sense to try it out with a vehicle that wouldn't be driven, anyway. SimpleNG has proven to be a very popular mod, and it pretty much does this (but with real-life vehicles). However, that was likely because there were so many vehicles added and they were all real vehicles, so people were more willing to excuse the lower quality. For an official vehicle, I think people would expect more out of it than just being a traffic car - especially something that's very commonly requested (like a modern pickup truck/SUV). AgentMooshroom5 mentioned in this post that the traffic AI has issues with very large vehicles, and multi-part vehicles would likely be complicated to implement.
I believe someone made a mod with NFS traffic cars, semis included, and they seem fine with freeroam traffic ai.
Because they are unrealistically light --- Post updated --- Its the same problem I had when making MertY the simplified traffic Cherrier Potent
honestly this may be a hot take but the idea of ST cars being lighter than playerchar cars just sounds like a good idea for tutorial mode edit: CAREER mode* god i'm tired
