More evidence that bikeshare is transit's friend:

In Champaign-Urbana (Illinois), pedal bikeshare increased bus ridership by 1%, and then upgrading to e-bikeshare grew it 1.1% more.

doi.org/10.1016/j.tra.…
This study found many bikeshare trips providing first-mile/last-mile transit access. Makes sense.

Another possible synergy: Bikeshare enables more residents to go car-free or car-lite, leading to more transit use (which is my own experience in DC).
This sounds reasonable, but studies indicate that Uber/Lyft reduce transit ridership.

"For every year after ride-hailing companies enter an urban market, rail ridership can be expected to fall by 1.3%, and bus ridership by 1.7%." bloomberg.com/news/articles/…

In @TheAtlantic, I argued that the USA must stop claiming that human error alone causes 94% of traffic deaths (~40k per year, and rising).

Beyond being incorrect, it’s a deeply damaging myth.

A 🧵:
theatlantic.com/ideas/archive/…
Laying blame on the driver (or pedestrian or cyclist) is convenient for many powerful forces in transportation. But it’s counterproductive.

People do make mistakes that lead to crashes. But more often than not, other factors could’ve prevented or mitigated the collision.
What if the road engineer designed a less confusing intersection? What if the truck wasn’t so heavy or tall? What if the cyclist had a protected bike lane?

Focusing solely on human error ignores questions like these.

The newly-passed infrastructure bill could bring major - and very positive - changes to auto safety.

Example: The bill requires that autos be equipped with tech to detect when the driver is drunk (and prevent them from driving). The alcohol industry fought this hard.

[cont'd]
The bill also pushes USDOT to (finally!) update the New Car Assessment Program (crash test dummy program), to evaluate the risk that car models pose to pedestrians and cyclists -- who are currently completely ignored.
Minimum performance standards for Advanced Driving Assistance Systems, addressing the wide (and confusing) disparities in what these systems can do right now.

The e-bikes are getting faster. Cities aren’t ready.

A 🧵 about my new article in @CityLab
bloomberg.com/news/articles/…
This month @VanMoof unveiled the V, a “hyperbike” capable of 37 mph - faster than the fastest Tour de France time trial.

VanMoof knows that regulations aren't designed for a bike like this, but CEO Ties Carlier told me he expects governments to adapt.
bloomberg.com/news/articles/…
In the USA, an e-bike that exceeds 28 mph falls into a regulatory limbo. State officials admitted to me that they don’t know how to treat it.

Is it a bike - or a moped, which would trigger extra rules for registration, helmet use, etc?

UPDATE on the federal e-bike tax credit:

Congress' new reconciliation language DOES include the e-bike tax credit -- and it's back up to 30% of the e-bike's cost (the House had previously cut it to 15%).
Other core elements remain the same-- still means-tested (starting at $75k income), still requires the e-bike to cost less than $5k.

Look at page 1285:
rules.house.gov/sites/democrat…
Also -- and this is important -- the reconciliation language would make bike and bikeshare eligible for commuter benefits (i.e., pre-tax expenses).

I’m in the Washington Post today, sharing 5 myths about highways.

Here’s a 🧵 with a quick tour:
washingtonpost.com/outlook/five-m…
Myth 1⃣: "Wider highways move traffic faster"

Nope! Expanded highways attract more car trips, which inevitably slows traffic down again. You can blame induced demand, a theory that economists (but not construction-loving state DOTs) have long accepted.
bloomberg.com/news/features/…
Myth 2⃣: "94% of human crashes are caused by human error"

Nope! Blaming the driver alone lets others off the hook, including engineers who design dangerous roads, car companies building heavier & taller SUVs/trucks, and cities underinvesting in sidewalks.

In @Slate, my take on the controversy around Dr. Missy Cummings’ appointment at @NHTSAgov — and what it means for the Biden admin's ability to address the recklessness of Tesla Autopilot and Full-Self Driving.

A 🧵:
slate.com/technology/202…
A Duke professor and human factors expert, Cummings is well qualified for the role, which requires working w/carmakers, tech co's, gov officials, and advocacy groups.

A backlash has come from the company whose pattern of disregarding safety gives it the most to lose: Tesla. Image
Cummings has been vocal about the dangers of Autopilot and Full-Self Driving (I interviewed her for this piece last December).

But that doesn't mean she's biased -- it makes her realistic and knowledgable, like Lina Khan criticizing Facebook.
