As far as commercialization of autonomous driving goes, also not much will happen for a few years. Back at Ariake, Ken Koibuchi tells me that the tech I tested today won’t be on the market before 2020, because that’s how long it takes a responsible company to test a quantum-leap like that, and that’s how long it will take to produce the still experimental sensor arrays in the required form factor and cost. Since I checked on that sensor last year, it already has slimmed down its size. From afar, the Lexus GS looks like a normal car, no rotating coffee-pot on the roof. Getting a bit closer, one notices the sensor under the rear-view mirror, and bulges over the c-pillar in the back. For a production car, those will have to go.
