For anyone interested, SCS announced a road-trip mode for ATS a little while ago, in which they plan to (at the very least) add a bunch of passenger vehicles - if not expand the roadways a bit in more touristy areas not typically used for commercial trucking. They also just released a (partial) list of the vehicles they plan to add, including:
Ford: 1967 Mustang with 390 Thunderbird Special V8, 2023 F-150 with 5.0 V8, 2023 F-150 Raptor with 3.5 V6, 2023 Bronco with 2.7 V6, 1998-2012 Crown Victoria with 4.6 V8
Dodge: 1970 Charger with 426 Hemi V8, 1996-2002 Viper with 8.0 V10, 2023, Challenger with 6.2 V8, 2025 Ram 1500 with 3.0 I6
Toyota: 1984-1987 Corolla GT-S with 1.6 I4, 1993-2002 Supra with 3.0 I6, 2024 4Runner, 2024 Sequoia, 2024 Tacoma, 2024 Tundra
And
Nissan: 1970 Datsun 240Z with 2.4 I6, 1998 240SX with 2.4 I4, Nissan GT-R, 2024 Frontier
The year ranges are because they put out a call for owners of the specified cars to contact them so that they can record audio samples from them. Didn't see Chevy on the list, so either they don't plan to add Chevy vehicles - or they're working with Chevy directly.
If you want a good "road sim", ATS is one of the best ones for a more organic and natural feel to driving, especially if you have increased traffic mods and enhanced AI to make some vehicles more aggressive/cautious. You can currently drive modded cars in the game, but the physics on them are still just tweaked Semitruck physics. With the upgrade to PhysX64 physics handling and dedicated passanger car physics, it should provide a much more realistic driving experience than just having modded cars.
If you have a proper racing wheel, frame, shifter/pedals, maybe a button box with ignition, and a VR headset - it will give you a fantastic driving experience to get acclimated to driving a bit, but again it's still no simulator since it's AI traffic doesn't behave like real drivers, and there are zero real road hazards. No pot holes, no black ice, no wind resistance or white-out conditions during storms, no deer/wildlife or pedestrian obstacles.
And I would consider having a VR helmet essential as it will make checking your gauges/mirrors/or even just turning around to look behind you as you backup far more true to life than simply flicking a mouse or analog stick.
