I'd have liked my school to do the same.

It's not just some small alarmist group raising a bell over nothing. We will run out of IPv4 at some point. Some estimates say two years, some say eight. Could be more, could be less. At any rate, we WILL run out. Why not adopt a clearly better alternative while we've got time? How can it be disadvantageous?

I consider myself relatively competent behind the wheel. I also consider a lot of people not-quite-so-competent. But while I have a healthy distrust for other drivers, I'll trust them over a computer any day. Either I'm driving, or the radar is. Perhaps there's a reason I'm not stopping before I hit that car. Perhaps it's a maneuver that I decide "You know what, rear-ending the guy in front of me is a lot better than [fill in the blank with something the computer doesn't know about]".

Only if they're alone in the woods.

Ouch.
