Todd W. Schneider recently mined data from the New York City Taxi & Limousine Commission to create a chart summarizing yellow taxi, Uber, and Lyft usage.
The data only runs up until January 2016, but here’s what he found:
“…yellow taxis provided 60,000 fewer trips per day in January 2016 compared to one year earlier, while Uber provided 70,000 more trips per day over the same time horizon.”
The Uber data only begins in 2015, but you can still see how quickly it is growing and how yellow taxis are losing market share. Five years ago, yellow taxis were reaching over 500,000 trips per day (a pretty amazing number) and in January of this year they were at about 350,000 trips per day.
It also appears that Lyft is struggling to gain traction.

What’s also great about Todd’s blog post is that he has set it up so that his chart will automatically update as new data becomes available. So if you’re interested in this topic, you should bookmark his post.

My friend Evgeny published a great blog post today called, On Car Ownership And The Future Of Transportation.
And in it he made the argument that instead of buying a car and an expensive downtown Toronto parking spot (average price: $40,000 - 60,000), most of us urbanites would be better of just taking a taxi or Uber.
This got me thinking: At what point does it really make sense to completely forgo owning a car? (Full disclosure: I own both a car and a downtown parking spot.) So I decided to dig into the numbers a bit more and compare 4 mobility options:
Owning a car ($25,000 upfront) + downtown parking spot ($40,000 upfront) and driving yourself everywhere
Taking a regular taxi exclusively ($3.25 base + $1.75 per km)
Taking an UberX exclusively ($2.50 base + $1 per km)
Or, taking a futuristic driverless car everywhere (here I assumed $1.50 base + $0.25 per km)
With the above numbers, I then assumed 15,000 km traveled per year and an average trip length of 15 km (so 1,000 trips per year). The trip length and number of trips per year matter because of the “base fare” that is charged when you take a taxi or Uber.
I also assumed that the cost of owning a car is $0.60 per km (estimated from this Globe and Mail article) and that there is an opportunity cost to NOT renting out your downtown parking spot ($200/month). That is, every month that you spend driving yourself around and parking your car, you are forfeiting parking revenue.
Finally, I looked at a 10 year time horizon and then “discounted” all the costs back to today’s dollars so that I could compare each mobility option.
So what did I find?

What this says is that if you’re driving 15,000 km per year (average trip length 15km), then you’re better off taking UberX everywhere, as opposed to going out, buying a car and parking spot, and driving yourself around.
But does this hold true at different travel distances?
Based on my model, once you hit around 18,000 km per year, then you’re better of with option 1 (owning a car). That’s because the per km savings associated with driving yourself around are enough to offset the upfront costs of the car and parking spot.
On the flip side, when you drop below 7,500 km traveled per year, even a regular taxi starts to make sense. That’s because you’re simply not traveling enough to reap the benefits of owning a car/parking spot. Again, high upfront costs; lower per km operating costs.
Of course, there are a number of things I didn’t consider in my model. For one, most people finance their car and parking spot (it is bundled into their home mortgage). So I’m sure there are ways that you could change the above outcomes using leverage.
At the same time, I didn’t account for the fact that when you’re being driven around (as opposed to driving around) you have the flexibility of doing work, responding to emails, and so on. If you want to attach a value to your time, then the scale would tip back in favor of taxis and Uber.
But all of this was really just to make one point: look how cheap it could be to ride around in a driverless car. When that becomes the reality in our cities, which it will, it’s going to completely transform our current beliefs around cars, parking, and many other things.
I guess that’s why General Motors just invested $500 million in the peer-to-peer ridesharing company, Lyft. They know the shit is coming.

Airbnb is a platform that connects people who have extra space with people who need space. It’s a peer-to-peer hospitality company.
Yeloha, which is a startup I just discovered today, is a peer-to-peer solar company based out of Boston.
In the same vein as Airbnb, it connect people who have extra roof space (that’s suitable for solar collection) with people who want to buy solar energy (but may not have a solar friendly roof).
Here’s an image from their website that explains how it works:

Basically, if you have a solar friendly roof, Yeloha will come and install solar panels on top of your place for free. You get to keep some of the energy that’s generated (about 1/3 apparently) which becomes a credit to your electricity bill. You are then known as a “Sun Host.”
The remaining energy gets fed back into the grid and, if you don’t have a solar friendly roof, you can purchase this excess energy, which also results in a credit to your electricity bill. The solar electricity is less expensive than the regular grid electricity. In this case, you are known as a “Sun Partner.”
I think this is a pretty neat idea. Neither party has to pay anything upfront. Both parties save money. And the result is more solar through a distributed and virtual net metering setup.
