It most likely is a big job to do these, but I think these are great ideas. Navi screens that don't only display the map (Reverse cameras, music player and some gauges that display power/boost at that current moment.) Comfort/Sport modes (Stronger FFB, different exhaust sound, better throttle response and different suspension settings.) More modern driving assistance features (Autonomous Emergency Braking, Lane Keep Assist, Adaptive Lights (Just to the point where they turn in the direction of the corner, but this isn't important, not many people play the game at night.).) Ambient lighting (Inside the car (This one probably requires a lot of work and it is a small feature.).)
I could say most of the points doesnt meet up with the point of the game, this is not city driving sim
Well driving modes have been talked about by devs, and we already have ESC modes. Ambient lighting is an inportant part of a modern car so that should be a thing if we ever get a modern car that isn't a facelift of an old platform. Driving assist features probbaly will only be the ones that affect the player, like the ETK system we cirrently have. Changing nav screens could come in handy in career mode but for sandbox driving the minimap/eSBR display style we currently have does just fine.
Those are components to the car, it has nothing to do with city driving. This isn't a game about crashing cars, this is a game about simulating vehicles accurately.
