Bloomberg recently interviewed the outgoing head of San Francisco's transportation agency -- Jeffrey Tumlin -- about the impact that self-driving cars have had on the city. Along with maybe Phoenix, San Francisco has the most direct experience. Robotaxis have already been operating in the city for four years.

It's an interesting interview. On the one hand, robotaxis have, according to Tumlin, gotten better than most humans at "seeing" and predicting the behaviours of pedestrians. They offer slow and steady law-abiding rides, which is arguably not how must humans drive. This is a safety improvement.

But on the other hand, robotaxis still represent a fundamentally inefficient use of roadway space. They take up just as much space as human-operated cars, but importantly, they offer a less frustrating driving experience. Meaning they tend to induce demand, much like ride-hailing platforms.

In a 2018 study by San Francisco County, they found that roughly 50% of the increase in vehicle miles traveled in the region was due to Uber and Lyft. So not surprisingly, there are important things that will need to be figured out as robotaxis continue to spread across our cities.

I also find the comparison in the interview between San Francisco and Phoenix to be particularly interesting. The former is walkable. The latter is not. And this seems to be creating a different experience with self-driving cars because robo or not, in Phoenix, traveling by car is pretty much the only option.

This is Map 2 from Toronto's Official Plan , dated January 2024. It shows the city's "urban structure", and one of the main things it tells us is where the city is anticipating growth. You have the downtown and central waterfront, urban "Centres", and then "Avenues." All three of these colored areas are where growth and intensification are encouraged. The problem, however, is that it still resembles a mono-centric city, with a dominant core and then mostly low-rise housing surrounding it. The Centres in the inner suburbs are relatively small and many of the Avenues are broken up without a lot of connectivity back to the rest of the city's grid. It sets us up for a divided city -- core versus the rest -- because different built forms naturally create different political priorities.

Now let's look at what Toronto has just proposed in terms of new Avenues (shown above in purple). This is the kind of thing that immediately gets me excited because, as proposed, it implies a significant upzoning for a large portion of the city and it creates a much more uniform urban structure. Here, we have a blanket of intersecting Avenues, which will open up a ton of new housing opportunities and make it far more feasible to build efficient transit and other mobility solutions across the city. In fact, I'd argue that this is one of the most important land use discussions taking place in Toronto today. It's foundational to moving us away from the anachronistic model of the car-oriented North American city.

Now we just need to make it happen, and then empower developers and builders of all scales to build housing and a mix of uses all along these purple lines. For more on this, check out the City of Toronto's Housing Action Plan .

Also on Conde Nast Traveler's list of the best places to go this year is Ho Chi Minh City. I've never been, but I would love to go. More importantly, though, check out the photo they used, which is of the city's first Michelin-starred restaurant, Anan Saigon :

From what I can tell, the building (and lot) is maybe 3-4m wide. And it looks to be 7 storeys (the top floor is partially concealed because of the angle of the camera).

On the first two floors you have what I am presuming to be the main restaurant spaces. On the third floor there is a bar. Maybe this is also part of the restaurant. And on the fourth floor you have Anan's pho restaurant (I checked their website).

Above that it looks to flip to residential. And then again above that it looks to be residential. Finally, on the top floor it appears to be more commercial in nature, so I'm guessing it's a rooftop bar for Anan. If anyone has been here, please let me know if I'm getting this right.

Regardless, this is a terrific photo and a powerful example of what's possible on small urban lots if you just let people build.
