These are two short videos of autonomous Cruise vehicles driving around San Francisco. Cruise, which is owned by General Motors, received a permit from the state of California to operate autonomous vehicles -- without a safety driver -- in September of last year. In November 2021, one of the cofounders of Cruise took the first ever driverless taxi ride in the company's history. And on February 1, 2022, Cruise announced that it was opening up to the public.

If you read the comments on Twitter you'll see that some people have found these vehicles to be hyper reactive to traffic lights and to do oddly long pauses at stop signs. So I guess they're not perfect. But oddly long pauses are certainly better than not stopping at all. Either way, this is a big deal. I'm not sure if these are the first unsupervised autonomous vehicles out in the wild, but they are easily some of the first.

There has been a lot of discussion over the last few years about autonomy being a hugely tricky technical problem to solve. One that is perhaps more difficult than a lot of people thought it would be at the outset. I'm assuming that this is at least one of the reasons why ridesharing companies like Uber and Lyft ended up selling off their AV divisions while searching for profitability.

But the market never gave up and it's pretty exciting to see this coming to fruition. Oliver Cameron is VP, Product at Cruise and the former CEO of Voyage (which was acquired by Cruise last year). If his tweets (above) are any indication, San Francisco is going to be seeing many more autonomous vehicles in the coming months.

This is going to have a profound impact on the unit economics for ride sharing companies like Uber, but more importantly it is likely to have a profound impact on our cities. Mobility innovations have a way of doing that. Some of the impacts might be negative, but I believe that many of the impacts can and will be positive.

As most of you will know, I am a believer in dense and walkable cities. I do not believe in planning cities around cars. And so that is not what I am advocating for here. My view is simply that I think autonomy grants us the ability to rethink our definition of a "vehicle." And maybe it becomes something that more closely resembles public transit. That could be a positive thing for our cities and something that draws people away from private vehicle ownership.

So I remain both optimistic and excited about what's to come.

Have any of you had a chance to ride in an autonomous vehicle? If so, leave a comment below or on Twitter.

We used Uber to get pretty much everywhere when we were in Rio de Janeiro. For reasons of convenience, cost, and safety, it just made the most sense. I can tell you that it felt a lot more valuable in place where you don’t speak the language and you’re acutely aware of being in the wrong place at the wrong time.

And since Uber is going public later this year (along with Lyft), it got me thinking about whether or not it is a stock that I would want to own. Are they destined for monopoly profits? Do they have a defensible business model? How powerful are their network effects? Having first-mover advantage doesn’t guarantee anything.

My initial thoughts are that the network effects for their core offering – single rides – don’t feel that strong. Sure you need a critical mass of drivers so you’re not waiting around too long, but at a certain point the response time is likely good enough. Rides are a commodity.

This arguably changes as you get into services like Uber Pool and Uber Commute, because more users on the network in close proximity to you can mean lower costs and higher service levels. But is there any sort of lock-in effect?

Many passengers and drivers seem to “multi-tenant.” In other words, many (or maybe most) people have multiple ridesharing apps installed on their phone and they will switch back and forth when it makes sense to do so. I do that when prices are surging. And drivers appear to be doing the same based on the Uber and Lyft emblems in their cars.

For a long time, Uber was the only show in town here in Toronto. Hailo only lasted about two years or so. But as soon as Lyft entered the market, both companies moved to aggressively discount their rates, and that is still going on to this day. This suggests certain things to me.
