LiDAR is essentially radar that uses light instead of sound
Radar doesn’t use sound. It sounds like the author doesn’t know the difference between sonar and radar.
This is why comments are so useful. I was already on the fence about viewing a site named
futurismand your comment made sure I will avoid it moving forward.Yeah, it uses radio frequencies. RaDAR stands for “Radio Detection And Ranging”. It uses radio waves (usually in the microwave bandwidth) to detect things. Basically, since those radio waves are affected by the Doppler effect, you can have a computer do some math to determine the speed of whatever those waves reflected off of. Because the Doppler effect changes a wave based on how fast an object is moving relative to an observer. So if you’re a stationary observer, you can figure out how fast an object is moving relative to yourself, purely based on how much that moving object changes the waves you’re reflecting off of it.
“We’re trying to have those conversations with Elon to establish what the sensors would need to do,” Baglino added. “And they were really difficult conversations, because he kept coming back to the fact that people have just two eyes and they can drive the car.”
Yes, and people crash cars all the time Elon…
If you want an autopilot with the failure rate of a human, then you might only need two eyes. If you want an autopilot with a near zero failure rate, you need much better telemetry data
