People who refuse to wear seatbelts always tell us "I can react in time and brace myself". They obviously do not understand the forces of inertia, and the simple formula m1v1=m2v2. Most people are unaware it takes about 0.75 seconds for your foot to start pressing the brake once you spot trouble. The same principle applies to your false confidence that you can protect yourself from slamming into the windshield in 1/100th of a second. You owe it to yourself, and your loved ones to wear your seatbelt. You must demand that all passengers in your car wear seat belts. They will not think you are foolish, they will respect you when they see you are adamant about it. And if you happen to get into an accident that everyone walks away from, you will be their hero.

Physics Lesson:
If you are traveling at 35 MPH and get into a wreck, due to the moment of inertia your 150 pound body has, you MUST to be capable of bench pressing about 600 pounds to keep yourself from slamming into the windshield. This is not made up, it is a force of nature fact. No human I know can bench press 600 pounds, much less protect themselves in the 1/100th of a second it takes to slam into the windshield at 60+ MPH. Remember, in an accident, the used car has already stopped, but you are still moving at 60+ MPH, thanks mostly to Newton's Law about objects in motion wanting to remain in motion until acted on by an outside force, i.e., windshield. Gosh, if only you had known about that silly little formula before you got into the used car! Should have paid attention in Physics lab!
