Which #s do carmakers use to market EVs? My conclusion, in @FastCompany: “Rather than auguring a future of useful & efficient EVs, automakers are emphasizing metrics that portend disappointed customers, wasted resources, & needless road deaths.” fastcompany.com/91227386/forge…
In US cities, ~2/3 of crash deaths occur on streets owned by the state – not local gov. Outdated, deadly state roads are preventing cities from building the safe, comfortable, and transit-friendly streets residents want. My deep dive, in @voxdotcom vox.com/future-perfect…
My latest story in Bloomberg CityLab: An interview with @BethOsborneT4A exploring what Trump's election means for US transportation policy. I have a thread with much more info on Blue Sky. Find me there: @DavidZipper.bsky.social bloomberg.com/news/articles/…

Everyone is being so nice to each other in DC today, like the other person is about to undergo an excruciating and risky operation
Cities and states must lead. Here are a few possible strategies. bloomberg.com/news/articles/…
A Trump presidency means the feds won't be restraining car bloat. This NHTSA proposal looks doomed. The path for reform now goes through states and cities, where officials can impose fees on the heaviest cars, outlaw truck lifts, and give smaller cars preferential parking.
Finally, the Biden administration is taking a stand against car bloat. @NHTSAgov has proposed banning SUV & pickup hood designs that are especially likely to cause head injuries. In @FastCompany, I explained why this could be a watershed moment. 🧵 fastcompany.com/91195993/car-b…
@oliviacgeorge @washingtonpost @postlocal Awesome, Olivia! Let’s grab a coffee when you make it to DC.
Impact of congestion pricing in Stockholm: - Car traffic ⬇️ 20% - Center city air pollution ⬇️ 10-15% "Congestion pricing isn't even a controversial subject anymore; it's more akin to talking about speed limits or traffic signals." cbc.ca/news/science/w…
"An e-bike won’t make sense for everyone. But, for those looking for a new way around town or to save on the high cost of owning a car, it could be a game changer. For me, it might be what makes me sell the Chevy." thebaltimorebanner.com/community/tran…
Researchers: "Car-centric neighborhoods really are boring." psychologytoday.com/intl/blog/the-…
As of today, Paris has banned thru-traffic in the center of the city. Cars owned by central zone residents/workers/visitors are still OK -- but no thru-traffic. Motor vehicle counts are expected to decline up to 30%. lemonde.fr/en/environment…
Many Vision Zero cities/states in the US now have more crash deaths than before they "committed" to VZ. VZ is a policy structure built around the idea that humans make mistakes, and they shouldn't be fatal. But in the US, it's often just a talking point. bloomberg.com/news/features/…
Warsaw is the latest European city to reach a new low in crash deaths. Vision Zero consistently works in Europe, but not in the US. Key reason: American officials resist doing the hard work of redesigning streets and slowing down cars. bloomberg.com/news/articles/…
Research I'd like to see: A study exploring how much of drivers' antipathy toward bike lanes is due to jealousy that cyclists don't get stuck in congestion.
The research says, "No, they do not." cbc.ca/amp/1.7358319
The research says, "No, they do not." cbc.ca/amp/1.7358319
Lessons for other cities from Denver’s e-bike rebates: - Expect *massive* demand at launch - Use drawings, rather than first-come,-first-served - Treat bike retailers as close partners - Get ready to see a lot more people demanding bike lanes bloomberg.com/news/features/…
Despite the popularity of Denver’s e-bike rebate, its days may be numbered. The reason: Colorado now provides a basic $450 rebate -- more than Denver – and the two discounts aren’t “stackable.” The city may reallocate voucher $ to other programs. energyoffice.colorado.gov/ebike-tax-cred…
E-bike rebates might be the most wildly popular transportation policy in the country right now. I visited Denver – the first US city to offer them– to see if reality matches the hype. In @CityLab 🧵 bloomberg.com/news/features/…
