Me, in Bloomberg:
Manhattan's congestion pricing program has been a smashing success. Other US cities have noticed.
Could Chicago go next?
Me in Bloomberg:
As autonomous vehicles scale, they're likely to cause crippling congestion. Two reasons:
1) Their users will take more and longer car trips
2) They often drive around empty
Result: More vehicles on the road, more pollution, and more traffic
Me, in Fast Company:
Finding parking can take a lot longer than Google Maps and Apple Maps suggest.
For instance, navigation apps ignore time drivers spend looking for a spot and then walking from it to their destination.
Result: Trips that are stressful — and travel planning that’s biased toward cars.
Americans drive a lot more than people in other rich countries.
If we didn’t drive so much, we wouldn’t die in so many crashes.
It’s a simple point, but one that NHTSA, traffic engineers, and many road safety org’s have yet to learn.

How safe are autonomous vehicles, really?
In Bloomberg, I got into the weeds with David Kidd of the Insurance Institute of Highway Safety.
His conclusion: “It’s still too early to say with any kind of confidence that they are safer than human drivers overall.”
Hey guys, I’m writing a book!
THE PRICE OF TRAFFIC will tell the story of congestion pricing, one of the best – and most controversial—policy ideas of the last half century. It will be published with MIT Press in partnership with Penguin Random House.
Know a great story about congestion pricing that needs to be told? An illuminating study that deserves more attention? A person with an inside angle on what went down in Singapore, London, Milan or NYC? Message me!
The research is clear: Cities have many reliable ways to curtail speeding.
Lower the speed limit. Deploy traffic cameras. Insert speed humps. Install road diets.
They all work – and most residents support them.
But implementation often feels like pulling teeth. In Bloomberg, I explored why.

Robotaxi companies are scrambling to expand in cities, but they’re ignoring rural America. They shouldn’t.
AVs could do a world of good in the countryside (and unlike in dense cities, they’d fit well into existing transport networks).

A strange but true finding about NYC congestion pricing:
Drivers’ time savings have overwhelmingly gone to those traveling *outside* the toll zone (i.e., driving from Brooklyn to Queens or within NJ) – not those headed into Manhattan.

A surefire way to make transportation more abundant and affordable?
Increase density.
In Bloomberg, I explained why: https://www.bloomberg.com/news/articles/2026-01-22/to-achieve-transportation-abundance-embrace-the-power-of-density
