Thousands of Teslas are now being equipped with a feature that prompts the car to break common traffic laws — and the revelation is prompting some advocates to question the safety benefits of automated vehicle technology when unsafe human drivers are allowed to program it to do things that endanger other road users.

Transportation emissions climbed back to two-thirds of pre-pandemic levels during 2021 — and that modest reduction was almost entirely attributable to decreases in air travel not driving, a new study finds.

Sustainability leaders are furious at the United States Postal Service for dragging its feet on ditching gas-powered mail trucks and other vehicles — and the agency doesn't seem to be seriously considering non-automotive mail delivery options, either.

As states begin cashing no-strings-attached federal infrastructure checks, U.S. DOT is pushing them to spend those funds on projects that will help end the climate and roadway death crises.

A prominent highway safety organization is still pushing enforcement and education in the fight to end roadway fatalities — again sparking controversy among advocates of better road design who say that driver behavior is already over-emphasized and policing subject to racial bias.

Most people who use shared e-scooters report higher levels of emotional well-being after a ride, adding to a mountain of evidence that sustainable transportation may be an overlooked tool in fighting America’s mental health crisis.

And as the bike shortages of the Covid-19 pandemic recently revealed, the absence of a robust domestic bike industry can itself become a barrier to getting Americans riding.

The majority of vehicle owners think that the installation of advanced driver assistance technology qualifies their car as a "fully automated self driving vehicle," a new study shows — and experts worry that over-confidence could cost even more lives as more semi-autonomous cars and their misinformed human drivers take to the road.

Federal and state agencies may be underestimating the amount of dangerous ammonia emissions that cars pump into the atmosphere by as much as a factor of five, a new study finds — and maybe more in urban areas.
