Holy crap I want to believe it'll work. Hypebot reports that an in-car hotspot solution will be announced at CES next week. The awesomeness of this cannot be questioned, if it works.
Whether it'll be seamless enough to stream internet radio at 60 mph on the BQE (hah...like anyone ever gets above 20 mph on the BQE...) remains to be seen. And in my opinion, $50 a month is too high for the averagethis guy to pay for vehicular connectivity. But it's sure a step in a cool direction.
