    1/ A personal highlight of 2019 was finding more time to write about how urban mobility tech is affecting cities, for better and for worse. A few articles seemed to hit a nerve, based on the amount (and passion) of reader feedback. A few notables:

    Last year I interviewed 40+ people to understand the mobility data debate when I wrote this article for . It’s frustrating to see the NY Times get so much wrong now. The topic is important!

    Another (important) thing: does not realize that Lacuna and Ellis & Associates are the same company? Lacuna *owns* E&A. He quotes people from both, implying they are separate entities. They are not. Honestly, this is a deeply troubling piece.

    Also, re: those who use shared mobility: "The ability to monitor their every movement is no longer alarming to users." It's not at all clear this is the case.

    What a strange take on mobility data in the NY Times. It's hard to see how MDS data from micromobility trips is "key to solving congestion"-- which is caused by autos, not e-scooters. Data alone can't fix cities' policy problems.

    "There's no magic moment when a carrier, or a nation, 'has' 5G." Valuable straight talk from , cutting through the 5G hype.

    Integrated mobility for the win! "AB2057 will require cities and counties to charge the same bus fare, to apply the same discounts for [transfers] from one bus line to another, and to define each population, such as youths and seniors, in the same terms."

    Prediction: With fewer idling cars in the way, biking in DC is about to get much more popular. Thank you, .

    Study based on Beijing’s lottery to award vehicle permits: “Getting a car had a significant impact on people’s physical activity. They walked less. They cycled less. They used less public transit. Those over 50 gained a considerable amount of weight.”

    If Elon Musk wasn't already bad enough for cities: Jealousy for the $1.3 billion Tesla received to build its gigafactory in Reno helped push Jeff Bezos to launch Amazon's race-to-the-bottom HQ2 competition.

    The mode shift seems high. In Arlington, VA, a survey of e-scooter riders last year found that around a third would have otherwise traveled by car, ride hail, or taxi.

    In Chicago's pilot, e-scooter trips led to a "42% reduction in ride-hailing, 23% reduction in driving and 18% reduction in walking." From a city perspective, the first two are great. The third is not.

    This is useful: 'Our cities were designed for an era where parcel delivery was the exception, not the norm. We’re only beginning to feel the effects when e-commerce becomes the default for entire categories of retail goods.'

    New micromobility research from & Luke Peters suggests that the number of devices in a network has a bigger impact on ridership than pricing, weather, or size of coverage area. 🤔 H/t

    With Techstars Mobility shutting down in Detroit, interesting to see the MA Governor allocate $250k in the state budget to launch a "mobility innovation hub" in the Boston area.

    Knowing some urbanist friends may disagree w/me: "With NYC and SF in the lead, is a car-free wave poised to sweep across urban America? Well, probably not. "...[F]ew American thoroughfares can match the hustle and bustle of Market Street or 14th St."

    Helbiz has dropped 520 shared e-bikes in DC, its first US deployment. $1 to ride and $0.15/min-- significantly less than Jump e-bikes ($0.25/min).

    My latest , in : I hate to be a downer on car-free streets, but banning all 🚗 isn't the best approach for most urban thoroughfares in the USA. Spare some ❤️ for 🚌 rapid transit and protected 🚲 lanes!

    Sad news: Techstars Detroit (formerly Techstars Mobility) is shutting down. I understand the company is shifting its transportation focus to Turin, Italy, where it manages a "Techstars Smart Mobility" program:

    City of Santa Cruz recently ran a pilot project offering $2 off JUMP e-bike trips to/from downtown. Great example of blurring lines between "public" bikeshare and "private" micromobility services.
