don't worry guys you just simply need to lock your cars. It's not like this hasn't ever happened while you're riding with someone else. Who actually rides in other people's cars? Who actually drives a stolen vehicle with no keys? Lol why would you hang out with other people when you can safely put on your seatbelt in your personal hatchback sport???
edit: this feature is supposed to be in the game dude, as the most realistic milsim of 2025 it is very common to eject from vehicles going 323km/h
