Highlighting rider ratings can reduce ride cancellations for groups vulnerable to bias, but other relevant information has a smaller, non-significant effect, from @KnittelMIT, Donald MacKenzie, Michiko Namazu, Bora Ozaltun, Dan Svirsky, and @StephenZoepf nber.org/papers/w33118

Wrapping up my first week on site at the U.S. Department of Transportation. It's a real thrill to be back in Washington and an immense honor to be joining Deputy Assistant Secretary Robert Hampshire's team at @Research_USDOT @USDOT

Argo naught

E.W. Niedermeyer@Tweetermeyer

Argo AI shutting down is a massive turning point for the entire driving automation technology sector. A seismic event.

This is also true of EVs. For example, many of today’s EVs & PHEVs won’t start if the 12V pack discharges, even if the HV pack is fully charged.

A good reminder that there’s lots of room for product improvement in eBikes as the market grows.

Reilly Brennan@reillybrennan

A reminder that ebike batteries and BMS don't yet seem ready for primetime. Manufacturer's note to me (after a major service issue) reminds me that it's pretty early for the ebike market if a consumer has to keep these steps in mind.

@kk_levine The phrase "false equivalence" comes to mind in this debate. "I have a right to exist" and "No you don't" are not equivalent statements.

Stephen Zoepf@StephenZoepf·13 Eki

"The most forward thinking of the nation's 3500-plus electric utilities see EVs 'more as a solution than as a problem to be solved'" This attitude is consistent with research findings showing that deeper EV-grid integration can be mutually beneficial. caranddriver.com/news/a41572989…

@LorenaSGonzalez They’re delicious! You can eat them by hand simply by twisting them open.

Lorena Gonzalez Fletcher@LorenaSGonzalez·6 Ağu

My favorite server at my favorite Vietnamese restaurant gave me a bag of these. She showed me how to eat them but didn’t know what they’re called in English. I need to make sure they don’t counteract my medication. Anyone know?

@AlexRoy144 Especially dad yokes. Those are the best.

Alex Roy@AlexRoy144·1 Haz

Not all yokes are created equal.

Bozi Tatarevic@BoziTatarevic

Good visual of why steer-by-wire with a progressive steering ratio is necessary in order to implement a yoke-style steering wheel.

Sometimes organizations need external forces to shove them in the right direction. I hope @harleydavidson uses this opportunity to lean harder into electrification. jalopnik.com/harley-davidso…

After 5 years with Spin, I am stepping down as CEO to hand the baton to Philip Reinckens from TIER. His focus will be combining best practices from Europe with the DNA that made us the #1 choice of cities. Thanks to the team for the ride of a lifetime. See you in the bike lane!

@reillybrennan eBike circa 2032 is going to be a return to the penny-farthing.
