I think there should be actually shattering glass. On the older cars when they didn't have this glass that wouldn't shatter as much. Also, I think the cars should give out a little faster because when I am with the AI, I can completely demolish them and they still run with no problem. Another thing, the wheels should fly off of the car on a impact that have enough force to get them off. Usually, they just tuck in the truck fender, looking like they are not there. Lastly, the tires should fall off of the rim, and fall apart with pieces flying all over the place.
All of the glass, except the windshields, shatters. None of these cars are old enough to be made before laminated windshields. At this moment, the only way to disable a car is to break the driveshaft or halfshafts. The devs plan to implement an engine damage system later on. Wheels can fly off. Just takes a lot of force. The tires will shred after they're popped, it just takes awhile.
