Google's self-driving car is capped by a $70,000 Lidar system that's more expensive than the car itself.
The Lidar is supported by an array of cameras and sensors, including this one mounted in the grille.
Inside the car, it doesn't look like much has changed, except for the big red emergency kill switch.
Google programs destinations and monitors the car's progress with a Lenovo ThinkPad laptop wired directly to the car's sensors.
One of the reasons that Google chose the Lexus RX450h was for its built-in ports.
Another camera faces front, mounted just behind the rear-view mirror.
The roof-mounted Lidar system spits out 64 lasers that survey the world 10 times a second to keep track of objects both stationary and mobile.
