In light of the disasters befalling those sixties-vintage boiling-water reactors at Fukushima, one has to worry about anyone still using ancient technology when new designs sit shelved for lack of vision. So I dug out that video of the IIHS crash test between a '59 Bel-Air and a 2009 Chevy.
Its not about whether something is intrinsically safe (life is not intrinsically safe, as anyone caught before that 23 foot tsunami learned), but whether we have made our modern technological devices reasonably safe as we have learned things. Obviously, technology changes in 40 years.
If we are going to use cars, bicycles, or nuclear power, we need to move to modern standards rather than wait for old examples to fail. I for one wouldn't want to go back to the flimsy centerpull brakes on my 1979 Motobecane Mirage, or its slippery-when-wet steel rims. Not to mention those huge five step jumps in its five speed cogset.
