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.

    LIDAR isn't the only sensor on a vehicle guiding the car. Plus, the chances that your lidar beam strikes the sensor of another lidar is so small that any occurrence, even on a crowded highway would introduce only a small amount of error that the computer would simply ignore.

    Strikes the sensor?

    What about the beam reflecting equally to a dozen different sensors on many different vars?
    What about deliberate acts, or surprising reflections off of fleck impregnated paint?

    Computers are notoriously bad at deciding what to ignore.
