Baidu will bring its driverless taxis to Europe next year via a partnership with U.S. ridehailing firm Lyft , as the Chinese tech giant looks to expand its autonomous vehicles globally. The robotaxis will initially be deployed in the U.K. and Germany from 2026 with the aim to have "thousands" of vehicles across Europe in the "following years," the two companies said.

CNET's key takeaways When I tested the Blink Outdoor 4, it was one of the first battery-powered models I had tried from the Blink security brand and, after testing dozens of outdoor cameras from different brands, I wasn't sure what to expect. Yes, Blink makes lofty claims that its lithium AA batteries last a ridiculously long time, but I've heard marketing lingo like that before.

After a few hours playing the upcoming Battlefield 6, it's clear the game is designed to be a mea culpa to fans: Trust us, we're bringing back the Battlefield you remember.

19 Best Barefoot Shoes for Running or Walking (2025), Tested and Reviewed

FAQs How do you define a barefoot shoe? Readers often ask why we don't include Altra or other zero-drop shoes. The answer has to do with how thick the sole is. Our definition of a barefoot shoe is that it should have a thin sole, or stack height as this is sometimes called. I put the cutoff at 10 mm or less (ideally less) to allow for good ground feel and toe splay, and to give you the kinds of feedback your foot needs to maintain natural movement.
