I was on two panel discussions over the last week and, as is the case with all real estate panels, the topic of parking invariably came up, as did the impact of autonomous vehicles.

There seems to be a general consensus that the advent of driverless cars will result in less demand for parking. Every developer I know is trying to build as little parking as possible and is thinking about how – when the time comes – they might convert their parking into something more productive. I have yet to speak to anyone who is building excess parking in order to prepare for autonomy.

Where there’s a split, however, is whether autonomous vehicles will represent a decentralizing or a centralizing force for our cities. Historically, new technologies have lowered transportation costs and encouraged decentralization. Before the advent of rail, the US population hugged the coasts, because it was cheaper to navigate across the Atlantic than it was to move inland.

A similar phenomenon also played out with our streetcar suburbs and with our car-oriented suburbs. These new technologies made it possible for people to travel further distances in order to get to work and other places. So it is not at all surprising that many people today are inferring that autonomous vehicles will produce this same outcome.

But there is a counterargument. 

We know that the demand for transportation services is highly elastic. Uber and other ride sharing apps have demonstrated this to us. Lower fares translate into dramatic increases in demand. So the opposing argument is that as the cost per kilometer drops – autonomous electric vehicles are going to be much more cost effective to operate – we’re going to see boatloads of induced demand.

This induced demand will then force us to look toward road pricing and other demand management tools in order to cope, which then begs the question: How much cheaper and more convenient will autonomous vehicles really be? 

At the same time, it is important to acknowledge that autonomous vehicles should correct many of the inefficiencies currently caused by humans acting like humans. There is also the opportunity to operate these autonomous vehicles more like public transit than as personal vehicles. And that will have a profound impact on urban mobility.

Still, it is not yet clear, at least for me, that autonomous vehicles will be the decentralizing force that many assume they will be.

Lately I’ve been having discussions around the future value of parking spaces in urban centers. So yesterday I tweeted out this poll:

Will parking spaces in cities become more, or less, valuable in the future? 💸 #AThisCity

The sample size is very small, but for what it’s worth, there are some/many people who believe that urban parking spaces will become more valuable in the future.

This is a reasonable assumption. 

Over the last couple of decades here in Toronto, I would guess that parking ratios for new multi-family developments have probably fallen by more than half. It used to be that you had to build 1 to 1.5 parking stalls for each unit and now we seem to be sitting somewhere close to 0.5. Although, there are also exceptions and some projects today are getting built with no parking.

So given that the supply side of urban parking spaces seems to be getting constrained and many cities are actively trying to encourage other forms of mobility, it’s not unreasonable to believe that parking stalls will only become more valuable. That’s why a new underground spot in Toronto might cost you $60,000 today and why some spots in New York can even fetch a $1 million. 

But this assumes that the demand for parking will remain more or less the same. What if it doesn’t stay the same? What if we were to experience a tipping point that rearranged urban mobility? What if the cost of driving became so high that people stopped driving at scale? In these scenarios, the demand side of the equation would change.

If you’re a regular of this blog, you probably know what I’m going to say next. But already I can think of two innovations that would contribute to the above scenarios: Uber and driverless cars.

Uber’s goal is to continually drive down the cost of transportation and eventually get you to no longer own a car. They know very clearly that the demand for transportation services is highly elastic and that the cheaper they get the more you will use them. And the way they get cheaper is by continually increasing the utilization rate of their drivers/cars. An idle driver/car is the enemy.

Of course, the other way to drive down fares is to remove the driver all together. And once you’ve done that, there is, in theory, no reason that a car should ever sit idle – like they do today. (The utilization rate for my car is around 2%.) And if a car is never sitting idle, then why would you ever need to park it? Certainly you wouldn’t need to park it as often as you do today.

All of this isn’t going to happen tomorrow, but I believe – despite the supply constraints – that we are going to end up with excess parking spaces in our cities. And that will mean that they are going to be perceived as less valuable than they are today. I also believe that it will eventually seem silly to drive your own car. 

What do you think?
