New technology costs big bucks. We know that. And yet the price tag for the rooftop rig that Google is using to test its self-driving cars costs something like $75,000 — in addition to the price of the car it sits on top of. That's a lot of money for a lot of ugly. Of course, there are only a few of these camera- and sensor-laden rigs in the entire world, and they're still in the beta stage and will be for quite some time (like everything that Google releases, am I right?). On-board driving assist technologies, like smart cruise control and 360-degree cameras, are becoming more widely available and cheaper, so these will likely lead the way toward driverless cars in the near future.
