The streets were mostly empty, but the map showed a traffic jam

Seeing traffic jams in Google Maps can really help you plan your route home from work. But a video posted this weekend seems to show that a traffic jam could be spoofed into Google Maps with nothing more than a bunch of phones piled into a little red wagon.

In the video, posted by Simon Weckert, a Berlin-based artist who focuses on examining the value and impact of technology, a man walks down some city streets pulling a wagon with 99 smartphones that all have Google Maps’ navigation turned on. As the man pulls the wagon, the streets get progressively redder on Google Maps. Those red streets would typically indicate a bad traffic jam — but the video shows that the streets were nearly empty.

Usually, Google determines where traffic jams are by pulling anonymized location data from phones running the Maps app. If there are a lot of phones on a road and they are moving slowly, Maps will show a traffic jam on that road. Lots of devices running Maps in the same spot is considered “proof” of a traffic jam, reported 9to5Google, after speaking with a Google representative.

Google jokingly told The Verge that it hasn’t “quite cracked” how to correctly track traffic data that comes from toy wagons, but that it can already distinguish between Google Maps data coming from cars and motorcycles in several countries.

It makes you wonder if Maps could be tricked in other ways, though. If a single person can fool Maps with a bunch of phones in a wagon, could others trick Google into creating actual traffic jams by using fake ones to re-route traffic?

Hopefully that doesn’t happen, but maybe Google will someday find a way to not show spoofed traffic jams like the ones set up in Weckert’s video.

California Governor Gavin Newsom vetoes the state’s “BitLicense” law.

The bill, called the Digital Financial Assets Law, would establish a regulatory framework for companies that transact with cryptocurrency in the state, similar to New York’s BitLicense system. In a statement, Newsom says it’s “premature to lock a licensing structure” and that implementing such a program is a “costly undertaking:”

A more flexible approach is needed to ensure regulatory oversight can keep up with rapidly evolving technology and use cases, and is tailored with the proper tools to address trends and mitigate consumer harm.

Get ready for some Netflix news.

Looking for something to do this weekend?

Why not hang out on the couch playing video games and watching TV. It’s a good time for it, with intriguing recent releases like Return to Monkey Island, Session: Skate Sim, and the Star Wars spinoff Andor. Or you could check out some of the new anime on Netflix, including Thermae Romae Novae (pictured below), which is my personal favorite time-traveling story about bathing.

If you’re using crash detection on the iPhone 14, invest in a really good phone mount.

Motorcycle owner Douglas Sonders has a cautionary tale in Jalopnik today about the iPhone 14’s new crash detection feature. He was riding his LiveWire One motorcycle down the West Side Highway at about 60 mph when he hit a bump, causing his iPhone 14 Pro Max to fly off its handlebar mount. Soon after, his girlfriend and parents received text messages that he had been in a horrible accident, causing several hours of panic. The phone even called the police, all because it fell off the handlebars. All thanks to crash detection.

Riding a motorcycle is very dangerous, and the last thing anyone needs is to think their loved one was in a horrible crash when they weren’t. This is obviously an edge case, but it makes me wonder what other sort of false positives we see as more phones adopt this technology.

Ford is running out of its own Blue Oval badges.

Running out of semiconductors is one thing, but running out of your own iconic nameplates is just downright brutal. The Wall Street Journal reports badge and nameplate shortages are impacting the automaker's popular F-series pickup lineup, delaying deliveries and causing general chaos.

Some executives are even proposing a 3D printing workaround, but they didn’t feel like the substitutes would clear the bar. All in all, it's been a dreadful summer of supply chain setbacks for Ford, leading the company to reorganize its org chart to bring some sort of relief.
