Car Crash Maths: Saved by a millisecond

August 22, 2021

*In 1970 the Victorian Government made the wearing of seat belts compulsory.

*The first government in the west to do so.

 *Within 14 months the other Australian states followed.

*The road toll in Australia dropped:

   1969       3,382 road deaths per year

   1988       2,887 deaths

   2018      1,135  deaths

Mathspig lived on a country police station before seat belts became compulsory and a number of kids she went to school with died in car accidents.

Three factors have reduced the road toll in Australia:

1. Wearing seat belts

2. Stopping drink driving

3. Introducing Airbags (from 1980s)

Our eyes can easily detect the blink (above) set a 300ms.

Ditto, the light flash (below), which is set to flash at  200 ms but it will drive you CRAZY if you look at it for too long.

The fabulous video (below) will show you the amazing details of the ms timing that saves lives in a car crash. You will see real car crash tests. And the frightening results too.
