All in all, I believe they reduce the risk of fatal accidents but do cause more non-fatal ones (there are probably some statistics floating around but I cba looking them up...)
Statistics seem to claim the opposite, according to Wikipedia they are actually safer, with up to 90% fewer fatalities because most collisions occur at an indirect angle.
I would have thought there were more obvious benefits to using hydrogen fuel cells:
lower heat produced during electricity generation means lower heat signature(not sure any missiles use spectrometry to find targets).
lighter than a internal combustion engine I think... also more joules per kilogram from the hydrogen.
quieter.

Teach the kid how to program in BASIC
NOOOOOOOOOOOOO! BASIC is evil!
Things that move are way more impressive than Printf("Hello World")!
Lego Mindstorms are a good start but the first thing that got me into engineering was playing with microcontrollors, AVRs are probably easiest to start with, dev kits like the Arduino (www.arduino.cc) are readily available.
They are easy and fun to code for and you can light up some LEDs or make small robots with ease.
Another little kit is a nice AVR based robot (code is a little out of date and references needed updating last time I used it)www.arexx.com
Say you have a friend named Martin. How much more likely are you to open emails saying they're from Martin and a FYI that his email address changed, which could (in a followup email) lead you to opening a trojan/virus?

Hey How are you doing?
That was with full access to facebook information and from her actual address. WOW thats good social engineering.
"Do you want your DNA to be stored indefinitely on a national database?"
a more useful question might have been 'would you be prepared to have your DNA on a database if it would act as a deterrent for crime and help bring criminals to justice'.
I realise this does not apply to Google, who seem to have brought new meaning to the phrase
'information is power'
