That's a misquote. Lidar is down to $10k from $90k. With the acquisition of Solid state lidar startup Strobe, they hope to get the costs down to ~$300. It's not clear if that's a per-unit cost, or a per-vehicle cost.
For sensors Cruise's Bolts currently use 14 cameras, 3 articulating radars, 8 regular radars, 5 Velodyne32 ultrapuck Lidar units, and 10 ultrasonic proximity sensors.
That's what Waymo's little bug-like car had. One in front, one in back, one on top, and one below each side-view mirror. Full coverage.
LIDARs are getting cheaper. Continental, the big auto parts maker, bought Advanced Scientific Concepts and is preparing to bang out low-cost LIDAR units in quantity.
Color TV cameras were once insanely expensive. This is the RCA TK-41, the first good color TV camera.[1] Each image orthicon alone (it used three) was about $10,000 in the 1950s. The camera in your phone costs about $10 and far outperforms a TK-41.
They require extremely high power outputs since the beam spreads out. This limits the range significantly but also makes it so that you need very powerful lasers, and the only way to make that eye safe is to use 1550nm light, which requires InGaAs photodetectors, which are much more expensive. In addition, you usually need SPADs which have very high noise levels. You can reduce this noise somewhat by cooling them, but that's very expensive and infeasible for automotive applications m
That's what I thought when I visited Advanced Scientific Concepts in 2003 and saw the prototype optics working on an optical bench. They pointed the thing out an overhead door and imaged the parking lot. It worked. But it was too big and too expensive for the 2004-2005 DARPA Grand Challenge.
Over time, ASC units got smaller, range and resolution improved, but pricing remained around $100K. Then Continental, the European auto parts company, bought ASC. Continental's units are smaller, cheaper and more rugged.[1] They haven't announced a price point yet, but being a major automotive parts manufacturer, they know how to get the price down on something when they make it in volume.
Continental is quietly coming out with all the parts for self-driving cars. They make the sensors, actuators, and high-reliability computers. They work on the little stuff, too, such as systems for cleaning the sensors while in use. All the things you need to do it, instead of just prototype it.
