Airbags for cars that have an air bag steering wheel were its just a smaller version of inflatable mat Breakable engine mounts were if you shift way too fast you can damage the engine mounts doesnt happen to automatic transmissions unless u use realistic mode on it but can happen on manual transmissions And the noise when you dont use clutch when shiftingand when you break ypur radiator the engine fan makes a broken noise because those 2 parts are colliding
SEARCH BEFORE YOU POST -Airbags have been proposed before many times before - Interesting idea but I've never really heard of this happening before irl - There's a noise when you don't use the clutch... that was added in 0.10 - That would happen in very certain occasions... usually broken radiators make a hissing/whining sound
