Back when Elon Musk was running Tesla, he was known for saying that LiDAR technology (basically laser beams that measure distances) was not needed to create full self-driving cars. And that's why their cars instead use a bunch of cameras to monitor the outside world.

Now, I'm not an engineer, but this never made much sense to me. Cameras can only see so far and they certainly can't see at night. So wouldn't laser sensing technology that can see 250-500 meters out — including at night — be greatly preferable when it comes to human safety, even if it costs more?

I'm reminded of what I said to my eye doctor before getting laser eye surgery many years ago: "This is not a transaction where I'm looking to be price sensitive. Get me the absolute best." And that's exactly how I feel when it comes to self-driving cars. I don't care if cameras are pretty good most of the time; I would prefer to have the best.

So which is the best? Damned if I know, but here's an interesting and also hilarious video by YouTuber and engineer Mark Rober where he compares the two technologies: cameras (i.e. Tesla) vs. LiDAR. I won't spoil it for all of you, but his last test is the "Wile E. Coyote test" and it's awesome.

At the time of writing this post, the video already has more than 11 million views and it seems to have been incredibly helpful to Luminar's stock price:

But now the internet is filled with speculation that he deliberately used the video to mislead people regarding Tesla's Full Self Driving capabilities and maybe even to pump's Luminar stock. (Full disclosure: I own a few shares, but this post is in no way any sort of investment advice.) I don't know if this is true or not. But I do think that the cars of the future will all come equipped with LiDAR.

This is going to be old news to many of you, but this past week I experienced Tesla's self-driving capabilities for the first time. And I must say that I was very impressed. It did everything from navigate stop-and-go city traffic to navigate lane changes on the highway. Overall, it makes my five-year old car feel pretty quaint. The software is that much more sophisticated and one has to assume that all of this autonomy stuff will only get significantly better as LIDAR becomes common place in production vehicles.

In other car news, North America appears to be narrowing in on an EV charging plug standard. It is Tesla's plug, but it is now appropriately called the North American Charging Standard (NACS) plug. And last week, Electrify America -- which is the largest non-Tesla, fast-charging network in the US -- announced that it would be adding the plug to its network. The company also happens to be owned by Volkswagen. So big and important companies seem to be coalescing around this plug type.

Lastly for today, here's a post by Fred Wilson talking about (1) bi-directional EV charging, (2) the apartment buildings he and his wife are developing, and (3) our ongoing transformation away from a centralized electrical grid to a decentralized one. What he talks about in his post is something that we are actually piloting in a few of Slate's office buildings right now. It's still early days, but I think it's really exciting. Tech seems to be enabling a broader shift toward decentralization. And in the case of our electrical grid, it's going to lead to a more resilient one.
