Joke taken....

Actually, show me any moving vehicle (land, sea or air) that does not have the
possibility of an accident happening taken into consideration when designing
it.  It is designing for these sort of loads that makes life tricky.
Examples:

Aircraft - inclusion of "black boxes", non-flammable interiors (well, they're
working on it), seat belts, emergency exits, and seats designed to withstand
the impact of flying into a mountain at 800km/h.
Ships - double bottoms, watertight partitions, pressure tested hatch covers,
lifeboats.
Cars - crumple zones, ABS, seat belts, padded dashes etc.
Trains - 2 purposes for the nose being shaped like arrows on high speed trains
1) aerodynamics, 2) gives a space to include collision protection - which I
believe is a bit like what the Tilt Train looks like, doesn't it? Trains have
more design freedoms involved in them, but lose some of those considerations
by their mass and speed.
