Something similar happened with airbags. You'd expect things to be safer but
I believe the statistics for fatalities works out about the same because
people drive faster.

As you say, people's tolerance for perceived risk is about constant.

So, question, do we fly differently when we know we have a parachute?

	I am reminded of when General Motors, about 10 years ago, made
	ABS brakes standard on one of it's models.  You can understand
	the excitement of the stats guys - here's a test with a great
	big sample size to prove how high tech (in this case, ABS) 
	improves safety.

	Well, guess what, it didn't.  The cars with ABS had the same
	accident rate as the cars that didn't.  In a huff, the stats
	guy packed up their briefcases and went home to sulk, and the 
	head shrinkers took over.

	Turned out, people started to rely on the ABS during braking
	(especially on water and snow) and they started to drive
	faster into the corners.  Tens of thousands of then.

	I don't think all the people who bought the new model year
	of car were necessarily irresponsible.  But the shrinks
	did conclude that people tended to operate at the same risk
	level, and so that margin of safety created by the high 
	tech was absorbed into the operation of the vehicle.

	I won't comment on the risk level tolerated (or even, gasp,
	enjoyed) by pilots who fly aerobatics, because we all know
	that recklessness is the act of perceiving risk, and taking
	it anyways, and none of us are reckless, right?
