Can't RTFA since work blocks Gizmodo (seriously? WTF?). However, my first thought after seeing the article summary was "You know, Grant drives this way in real life all the time on Mythbusters."
Where I work, there are not supposed to be any hotspots available. I was about to vote zero since that's what *should* be available, but to make sure I voted properly I opened up WiFiTrak on my iPod and checked. I was rather surprised to find there is one in range of me, but it's just someone's Android phone running G1 Tether. I was able to connect and get an IP address, but unable to use the connection for anything involving the outside world.
