AUSTIN, Texas-At the first day of the SXSW Interactive festival, George “Geohot” Hotz announced an updated business plan for his company Comma.ai, all while revealing a new piece of hardware that will be given away, as opposed to sold: the Panda. The small circuit-board device comes with an ODB2 connector on one end, which Hotz described as compatible with any car made after 1996 , and a USB port on the other.
