One caveat, if you're planning on using that helmet cam to record yourself being a tool tooling around: the resulting video can be be both entertainment and evidence. Police in New Zealand arrested a bunch of "stupid hoons" who posted a three-minute video clip to the Web that included them making repeated attempts at a four-wheel drift in a Subaru — apparently converted to full rear-drive — before slamming the car into a tree. They're getting community service, though the car is already beyond help. [Thanks to Stephen for the tip.]
