Ada orang diturtlekan dalam kereta. 
How do I know?

Wah....this airbag also not bad, can protect face from those pcs of glasses. Can save a lot of plastic surgery money.

btw installation of 3rd party airbag is not recommended, coz if malfunction might activate and unlike proper inbuilt airbags, it might opened to hard, crash you head to the back of your chair and break your neck. The height, etc is not fully customized for the car thus also might suffocate the drivers and passenger as well due to height, weight, etc differences. Those inbuilt airbags that comes with car HAS BEEN FULLY TESTED for the car seat with the height, weight, distances, impact strength adjusted AND TESTED numerous time that it can work effectively for the car it was installed in. No so for 3rd party airbag.

Go one up better. Why use car? Should go use bicycle. At least, no service also OK. 

To all those muthafackers who wants to change jobs.
