Electric scooters are an unsanctioned form of mobility here in Toronto, mostly because people think they're dangerous, but also because I think people are worried about them cluttering up our sidewalks.

The problem with this position is that electric scooters are also a lot of fun to ride and people seem to find them useful. The last time I rode one was in Paris and it seemed perfectly safe to me, though it may have been because there were two of us on it and we were kind of overloading the thing.

In any event, lots of cities either have them or are piloting them. Seattle just finished year one of its pilot program and here's what they learned:

• From September 2020 to October 2021, Seattle saw 1.4 million trips taken by over 260,000 riders

• Electric scooter ridership greatly exceeded that of public bicycles, with 300,000 scooter trips taken in September alone, compared to about 35,000 bike trips

• 54% of surveyed scooter riders said that they would have taken a taxi or driven their personal vehicle had a scooter not been available

• 21% of riders said that they used it to connect to public transit (helping to solve that pesky last-mile problem)

• 17 collisions involving a scooter and a car were reported during the pilot year (though, for what it's worth, some/many of the incidents involved a scooter that was privately owned and not part of the actual pilot program)

As much as I love riding a bike, it's a bit more of a commitment compared to riding an e-scooter, which is why I think the numbers look the way that they do here. Not everybody wants to bring a change of clothes and shower at the office.

So I think it's really too bad that Toronto just shut these down before exploring ways to make them both safe and useful.

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.

The Institute for Transportation & Development Policy (ITDP) is a non-profit group that works all around the world -- everywhere from Jakarta to Rio de Janeiro -- to design and implement both transport solutions and policies that help to make our cities more livable, equitable, and sustainable. If you're interested in learning more about the kind of work that they do, you can download a copy of their latest annual report, here.

Most recently, the group published a report called, "The Compact City Scenario - Electrified." In it they argue that two things need to happen together if we are to move humanity toward net-zero carbon emissions and reduce global warming to less than 1.5 degrees Celsius by the end of the century. One, we need to fully electrify our transport (which I think is fairly obvious at this point). And two, we need a modal shift.

To be even clearer, ITDP argues that both of these things need to happen at the same time in order to successfully hit our targets. Full electrification of our transport without any sort of modal shift isn't going to cut it, and the same is true for a modal shift without electrification.

Why all of this is important is because electrification is in many ways just a technical problem. We need electric vehicles, we need batteries, and we need the infrastructure in place to charge these vehicles. Among other things, this has meant building new charging stations, retrofitting existing buildings, and encouraging/requiring new buildings to make provisions for a future with predominantly electric vehicles.

But for the most part, EVs allow us to continue living the way that we have already been living. Just instead of pumping gas, we now plug in our cars at the end of the day. On the other hand, encouraging a modal shift is a fairly significant behavioral change. Though we know that one of the most effective ways to encourage less driving is to build more compact cities.

This means changing the way we live. Changing the way we get around. And accepting more intense forms of development in our own backyards. It is fundamentally linked to land use planning and so it is going to be much harder to achieve. But if you agree with the above report, we won't be able to meet our sustainability goals without it.
