WTF...
Can't understand why people won't belt up. You don't have anything to lose. It's not too uncomfortable (infact not at all, unless your height is too low), easy to wear, easy to remove. Moreover, if the car is equipped with airbags, it is more dangerous.
On a lighter note, only COMPLETE idiots will buy this. Partial idiots will go to a garage, tell the mech to cut a seat belt of any rotting vehicle, take the hook and use it. Rs. 270 saved.
Smart guys will just fasten real seat belts.
