This is an interesting point for anyone thinking, "we didn't wer seatbelt's in the 70's and we were all fine!
The risk of being involved in an accident and being hurt or killed whilst travelling on the roads has diminished over time.
1938, there were 314 casualties for every 100 million kilometres travelled while in 2011 there were 41 casualties per 100 million kilometres travelled.
For example, between 1939 and 1941 the number of fatalities averaged around 8,700 per year, over three times the annual number killed today.
Since the 1970s the number of road deaths has fallen considerably, from over 7,700 deaths in 1972, to 1,901 in 2011.

AYBU? Most people will think you are. You wouldn't play Russian roulette with a gun, but you are with your kids having a potentially life limiting brain injury the next time they have a little spill.
Oh, and if you aren't wearing one either, are you really happy with the picture of your children watching you die? Or seeing you every day unable to look after them any more?
It's your call OP!
