Sadly some folks stupidly maintain that they should be at complete liberty not to wear seatbelts, despite their proven worth in saving lives.
Snopes.com documents the true and sad case of a anti-seat belt campaigner who tragically is killed within months in an accident which he would have survived had he been wearing his seat belt.
On this topic it's well worth reading a Malcolm Gladwell article first published in The New Yorker -- gladwell dot com--Wrong Turn: How the fight to make America's highways safer went off course.
The synopsis is that the US authorities made a fatal decision to push passive restraints such as airbags without also promoting seatbelts. An airbag is a supplementary restraint (SRS) and is relatively ineffective compared to a seatbelt alone - of course the combination of seatbelt and airbag is best. The 'experts' believed that 'machines' not 'men' were the answer - spend the money on gizmos not education. The result was that thousands of Americans died because they were denied the public education that their compatriots in other parts of the world were given, such as UK, Australia and New Zealand.
Physics is the law of nature. We can't escape the consequences of physics, particularly driving a potentially lethal weapon on slippery road. Yet there seems little effort (at least in my country - Australia) to ensure that learner drivers are also learning the laws that will seriously impact their safety (and that of others) on the open road. We should resurrect Julius Sumner Miller and have him posthumously teach us physics in the real world. "A car skids off into the bushes. Why is it so?"
