On November 3, 2007, six vehicles made history by successfully navigating a simulated urban environment—and complying with California traffic laws—without a driver behind the wheel. Five of the six were sporting a revolutionary new type of lidar sensor that had recently been introduced by an audio equipment maker called Velodyne.
A decade later, Velodyne's lidar continues to be a crucial technology for self-driving cars. Lidar costs are coming down but are still fairly expensive. Velodyne and a swarm of startups are trying to change that.
Some experts believe the key to building lidar that costs hundreds of dollars instead of thousands is to abandon Velodyne's mechanical design—where a laser physically spins around 360 degrees, several times per second—in favor of a solid-state design that has few if any moving parts. That could make the units simpler, cheaper, and much easier to mass-produce.
Nobody knows how long it will take to build cost-effective automotive-grade lidar. But all of the experts we talked to were optimistic. They pointed to the many previous generations of technology—from handheld calculators to antilock brakes—that became radically cheaper as they were manufactured at scale. Lidar appears to be on a similar trajectory, suggesting that in the long run, lidar costs won't be a barrier to mainstream adoption of self-driving cars.

AMEN!
"Weak minded" single though people are building these cars. Come on now we have multiple "pick ups" on backup sensors / bumpers, MIR, CAT scanners, and our own human build. Following Biology, use 3 rows of 2 at least eyes... 2 low (bottom of bumper), to medium (hood level), to high (roof level). Then you have distance calc in both horizontal and vertical giving below fog / little kids watch, as well as look around distance. So if the top cannot see ahead, but bottom can, at least you can slow the speed of vehicle to drive with-in head light range.
Mapping the roads is another poor idea to determining where a vehicle can drive. It is should always be what it can see (as in human sight). Us with long winding drive ways, will have to leave the vehicle at the road and walk home, since the drive is not mapped. The only reason for LIDAR right now, is the maps they are using are a single lined... So work areas and flag men would make cars inoperable.
