Escape Tip is easy fix for life and death situation

Imagine you're trapped in a submerged vehicle with no apparent way out. You've unbuckled your belt and you're ready to get the F out of Dodge when you realize the door won't open. Break the window, you think. Unfortunately your fists pounding on the glass aren't enough to break the window.
Believe it or not, according to this Gizmag article, 338 people drowned in the U.S. in 2003 due to car entrapment. Egression Technologies has designed a very simple and effective solution to that it believes should be adopted as an industry standard. Its Escape Tip Vehicle Safety System is merely a metal tip extension on the male-end of a seatbelt that can easily break the window of a submerged vehicle when its occupants are ready to leave. Though it's a minor point, we wonder if a tip like the one pictured would actually be a liability concern for automakers.
