The only way to prevent gigantic SUVs & pickups from killing pedestrians is to reduce car bloat.

Technology alone won’t do it – even if automakers claim otherwise.

Me, in @Slate 🧵

slate.com/business/2024/…
Context: Oversized vehicles are deadly for everyone else on the street – and especially pedestrians.

They convey more force in a crash, take more time to brake, have huge blind spots, and are more likely to strike pedestrians’ head/torso.

Odds are good that your favorite European piazza/plaza/place used to be a parking lot.

Great story from @aitorehm with before/after pics:

"0-60 time" is a car metric that needs to die.

Even today’s slowest cars are quick enough for normal driving. Blazing-fast acceleration is pointless, and it shreds tires while endangering others on the street.

Me in @FastCompany 🧵

fastcompany.com/91165821/how-f…
0-60 times emerged in the 1940s, the brainchild of a car dealer and auto journalist named Tom McCahill.

In the 1950s, a now-pitiful 10.5-sec 0-60 time on a sports car was something to boast about.

The biggest source of urban noise? Motor vehicles.

In @CityLab, I wrote about the quiet (and healthy) pleasures of car-free and car-light neighborhoods.

🧵

bloomberg.com/news/articles/…
There’s an urbanist adage that cities aren’t loud; cars are loud. It’s really true.

~50% of urban noise is attributable to cars.

Everyone pays the price. Example : Researchers found that even mild traffic sounds make food taste worse.

US transportation agencies keep claiming that expanding highways will reduce climate change.

That's absurd.

In @voxdotcom I explained why. 🧵

vox.com/future-perfect…
State DOTs (and the feds) regularly argue that adding highway lanes will reduce emissions.

Blue states, red states – they all do it. Example from Caltrans below.

Source: latimes.com/california/sto…

Oversized SUVs and trucks worsen a slew of societal problems, including crash deaths, climate change, and tire pollution.

But rather than restrain car bloat, federal policy has actively encouraged it.

In @voxdotcom I explained how. 🧵

vox.com/future-perfect…
First, a bit of context.

US cars have grown enormous. SUVs and trucks comprise 80%+ of new vehicles, up from ~25% in the 1970s.

SUVs and trucks steadily gain pounds and inches as models are refreshed.

This @FT piece is the best examination of US crash deaths that I've seen in ages.

The US is so bad at this: "Even after adjusting for distance driven, US fatality rates remain 2x the rich-world average."

Here's a quick 🧵 to share insights (paywall).

ft.com/content/9c936d…
Note that the US pedestrian safety crisis revolves around a few exceptionally dangerous states (looking at you, Texas and Florida).

Many relatively safe states (like those in New England) are on par with other rich countries. The Southeast and West are not.

Fifty years ago, William Whyte studied how New Yorkers schmoozed, sat, and relaxed the small open spaces available to them. This 1980 treasure was the result.

Join me as I share a few timeless lessons. 🧵 A key urbanist insight: “Supply creates demand.”

Comfortable urban spaces attract people happy to find a place to chat, eat, or read.

It's also the core idea behind induced demand, which explains why highway widening is futile (and why good bike lanes create more riders).

Oversized SUVs and trucks kill people in crashes, catalyze climate change, and widen inequality. And the problem is getting worse.

A 🧵 about my deep dive on car bloat, in @Slate @Slate “Car bloat” describes the shift in new car sales toward increasingly massive SUVs and trucks.

In 1977, SUVs and trucks comprised 23% of US car sales. Now they are over 80% -- and individual models keep adding weight and height.

Today is World Day of Remembrance for Road Traffic Victims. #WDoR2023

Notably, Americans are 2-5x more likely to die in a crash than those in peer nations. And the gap is widening.

Here are a few often overlooked ways to reduce the carnage. 🧵

nytimes.com/2022/11/27/ups…
1) Invest in mass transit

Buses and trains are 30-66x safer per passenger mile than driving.

Places with strong transit systems have more transit trips and less driving. They therefore have fewer crash deaths.

slate.com/business/2022/…

Last week the National Transportation Safety Board recommended that speed-limiting technology be required on all new cars.

It’s an excellent idea. @USDOT should do it.

My latest in @FastCompany. 🧵 below

fastcompany.com/90985257/you-s…
Consider this horrific crash last year in North Las Vegas.

A man on cocaine and PCP drove his Challenger at 103 mph through a red light, smashed into a van, and killed himself and eight people.

Speed-regulating tech could’ve prevented it.

cnn.com/2022/01/30/us/…

This is the best series on road safety I’ve ever seen.

Last week @nbcdfw ran a multi-part investigation into Dallas' epidemic of car crashes.

Rather than blame drivers, the story delves into speed, street design, and Vision Zero's failures.

🧵

nbcdfw.com/investigations… Context: It’s hard to overstate how terrible Dallas is at road safety.

The city has more deaths per capita than any US city of >1M. Many of the most deadly roads are managed by TxDOT, outside the city's reach.

For the first time, the EPA is investigating the environmental harm caused by tires.

The federal government is finally acknowledging that tailpipe emissions are just one of the ways that cars befoul the planet.

Me in @Slate. 🧵 below

slate.com/technology/202…
The chemical in question, 6PPD, makes tires more durable. It turns into 6PPD-quinone when exposed to air.

In 2020 @UW researchers published a bombshell study blaming 6PPD-quinone for the collapse of coho salmon in the Puget Sound.

I visited Pontevedra, a Spanish town whose motto is “fewer cars, more city.”

In 24 years, traffic fell 97% in the historic center and 53% citywide. And Pontevedra is flourishing.

In @FastCompany, here are 5 lessons from Spain’s car-free pioneer. 🧵
fastcompany.com/90952175/this-… @FastCompany When Pontevedra Mayor @Lorespontevedra was first elected in 1999, the city was in the doldrums.

Its economy was sputtering and younger residents were leaving.

The new mayor thought he had a solution: Get rid of the cars.

What happens when an entire town putters around on golf carts?

To find out, I visited Peachtree City, GA, an Atlanta suburb where most families own one.

TLDR: It’s pretty awesome.

A 🧵 about my deep dive in @business/@CityLab

bloomberg.com/features/2023-… Peachtree City was planned in the 1950s in then-rural Fayette Co. Its design drew from New Towns that emphasized green space & a cohesive urban plan.

Peachtree City would have streets and roads, but also a network of car-free paths.

Welp, it seems I'm not the only one who sees car bloat as a major problem -- one that we ignore at our own peril.

This thread received more comments than anything else I've tweeted, by a wide margin. Most were positive. (cont'd)

There was some interesting pushback. (I'm ignoring meltdowns from the jabronis w/huge trucks and thin skins)

Here's Ford's comms lead, trying to deflect. I don't blame him -- Ford doesn't offer any sedans in the US; its profits depend on big SUVs/trucks.

I’ve spent much of this year learning about car bloat, the process through which smaller vehicles are being replaced by increasingly massive SUVs and trucks.

What I’ve learned: Huge cars are terrible for society, often in ways that are hidden.

A summary 🧵 First, some basic info:

🔹 >80% of US car sales are now trucks/SUVs. Europe is behind, but catching up.
🔹 Models keep expanding. Ex: The 2023 F-150 is ~800 lbs heavier and 7 in taller than in 1991.
🔹 EVs can make the problem worse due to huge batteries.

Crashes kill 43,000 people per year in the US.

Self-driving car companies claim to have the solution.

I call bullshit. 🧵 below
slate.com/technology/202… To be clear, 43,000 crash deaths per year is horrific. The US has 2x to 5x more traffic fatalities per capita than other rich countries.

@SecretaryPete right to call it a “national crisis.”

You might’ve noticed a lot of recent news about robotaxis in San Francisco.

That’s b/c California officials will soon decide whether to let Waymo/Cruise deploy unlimited AVs, something the city vehemently opposes.

Much is at stake. An explanatory🧵
washingtonpost.com/technology/202… Being the urban hub of Silicon Valley, San Francisco has been target #1 for robotaxi companies, esp Cruise and Waymo.

The city itself has no power over these vehicles on its streets; it doesn’t even receive data about how many are deployed.

New report finds that over 8,000 pedestrians were killed on US roadways in 2022.

Jimmy Carter was president the last time that happened.

https://t.co/FuMwGTdFi1ghsa.org/resources/Pede…
@GHSAHQ The US is terrible at roadway safety in general -- but we are truly abysmal at pedestrian safety.

Awful to learn of this fire last night.

Not much info yet, but it's worth noting that such fires virtually always involve heavy-duty, cut-rate vehicles from abroad that are improperly serviced. E-bikes from established brands/retailers are very safe.
nytimes.com/2023/06/20/nyr… Battery fires are a serious issue, one that must be addressed. But it's a problem that involves sketchy models sometimes used by deliveristas -- not the average person.
