Last week, Uber announced something called "digital tasks." These are simple, quick tasks that drivers can do when they are not driving — things like recording a voice note in a person's mother tongue, submitting a document in a different language, or uploading images of everyday items (such as a menu or storefront).

This is Uber expanding its data-labeling and AI-training business, and they are positioning it as a "new way to earn" for drivers. But another way to think about this move is that it's a way for Uber to start to repurpose its workforce in preparation for a world where human drivers are far less essential to the business. That feels like the case to me.

On a related note, Waymo also announced last week that it will start operating its autonomous ride-hailing service in London, beginning in 2026. This is another first for the company: the first commercial operation outside of the US. Though they are also driving vehicles around Tokyo in preparation for eventually launching there.

Things continue to happen. As a casual observer of this market, Waymo feels like it is out front, which often makes me wonder about Tesla's sky-high valuation. Does the market really believe their Robotaxis have more potential?

In theory, this could be true. Their decentralized model — where individuals own the vehicles and plug them into their ride-hailing network — could allow them to scale quickly. But this is less proven — they're still in the pilot/validation phase. They also seem to chronically overpromise.

Regardless, I would really like to see Waymo launch in Toronto in the near future. As I understand it, regulatory barriers are the problem. I hope whoever is in charge is working on fixing this.

One thing that I do not do on this blog is provide investment advice. And this post is certainly not that. But here's an idea and thought exercise that relates to urban mobility. Let's assume you own a personal vehicle that is currently valued at US$30k, and that this car is what you use to go about your daily life. Now imagine that you sold this car today, harvested all of the proceeds, and invested them into the following three companies: Uber, Alphabet, and Tesla. If you did this equally, your US$30k would end up as the following (based on today's share prices and if rounded down):

• 111 shares in Uber ($89.56/share)

• 49 shares in Alphabet ($201.42/share)

• 30 shares in Tesla ($329.68/share)

Then, instead of driving yourself around, you'd put the money that you would have normally spent on insurance, gas, and maintenance toward Ubers and Waymos (assuming Waymo is available in your city). Perhaps you even own a parking spot that could be rented out for an extra few hundred dollars each month. Whatever the specifics, let's just assume that what you used to spend to operate and service your car is now being spent on getting around using ride sharing services. It's a wash. So the only difference is that instead of having US$30k tied up in a depreciating asset, you're now part owner of the above three businesses.

This, once again, is not investment advice. I personally don't know how to make sense of Tesla's current valuation. There's a hell of a lot of optimism being priced in. I'm simply picking these three companies as a way to bet on Waymo's autonomous vehicle program (which is currently in the lead), Tesla's robotaxi promises (which, who knows, could actually materialize), and the fact that Uber might still remain the dominant marketplace for rides (though there's already evidence that Waymo is on track to overtake Uber in San Francisco within the next ~8 months).

It's not clear who will be the primary beneficiary of this shifting mobility landscape. Is Tesla right about LiDAR not being necessary? Will human drivers (and therefore Uber) still be needed to manage peak demand loads? Is the asset-heavy approach of owning AV fleets the wrong way to go about things for Waymo? I think it all remains to be seen. But I also think it's clear that autonomous vehicles have arrived and that urban mobility is changing right now, as we speak.

So I think there's a relatively high probability that everyone who owns a personal vehicle would be better off if they did what I am suggesting in this not-investment-advice-don't-do-what-I-write blog post. In other words, if we freed ourselves of the old ways and made some bets on the future. And that's ultimately the purpose of this post. It's so that you and I can come back to it on August 10th, 2030, and see how I did with my prediction. The reminder has been set.

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.
