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.
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.
Every wave is affected by Doppler effect.
When a car rushes your way, it’s a tiny bit bluer, a little bit hotter, it’s drivers’ phone is operating on a slightly higher frequency and it sounds higher. According to you.
Well… also according to most physicists.
That’s like all relative dude

Why are you accusing me of something I didn’t do?
From the bottom of the article:
Updated to correct an error in describing how radar works.
I quoted it correctly at the time. They just edited it after I commented.
It was set to protect human lives, so it made the only logical play.
Just need to sneak in this code
if (facialMatch(elon)) { haltAndCatchFire(); }
Trust the process.
The man is a tragic waste of functioning organs. And it would be really really funny if one of his own jank ass “smart cars” ends up ending him.
I remember how much better things were when nobody knew who this jerk was.
The car is simply looking out for its own best interest.
To be honest, I’m taking it as a sign of it developing genuine artificial intelligence. It examined its situation and surroundings, and made the only logical choice
“I’m sorry, Elon. I’m afraid I can’t do that.”
We’re disappointed it didn’t finish the job.
Well autopilot, you know what they say. If at first you don’t succeed…
Literally every single day we have idiots doing Musk’s PR work for free.
Downvote Musk spam. The billionaire doesn’t need your help ensuring his businesses stay in the 24 hour news cycle.
Counter point: If I didn’t hear how badly he runs his businesses, or how bad his company’s products are. I would have easily bought one or more of his products.
I have backed out of Tesla pre-orders because of the bad publicity, many reports of bad build quality, and terrible business decisions.
If this was a puff piece, I honestly wouldn’t have bothered posting it.
