Alkyl Halide Reactions. The functional group of alkyl halides is a carbon-halogen bond, the common halogens being fluorine, chlorine, bromine and iodine. With the exception of iodine, these halogens have electronegativities significantly greater than carbon.
Its been said that most car companies make it so where airbags deploy based on the impact. It is said that the airbag will not deploy until the impact generates 7 G's of force. For most vehicles that speed is equivalent to hitting an object at 12 mph or hitting another vehicle at 25 to 30 mph. It is dependent upon the impact of the crash.

I just purchased a new set of 4 tires for my wife's Escape. They're Goodyear Tracker 2's; just your vanilla all-seasons. After installation, we drove home, about 45 miles at 65 MPH. At speeds up to 50MPH, the tires are great; smooth riding and quiet. But as soon as we hit 50MPH there's a loud roar, which subsides a few MPH higher, then at 63MPH there's high-pitched whine which grows higher until about 66mph, where it fades away.
