Tesla has been accused of exaggerating EV driving range in the past, but it’s now facing allegations that it’s trying to minimize complaints about performance. Reuterssources claim Tesla had a secret “Diversion Team” in the Las Vegas area that aims to cancel range-related service appointments. If a customer complained that the range didn’t live up to marketing claims, advisors in the team would tell owners that Environmental Protection Agency (EPA) range figures were just predictions, and that battery degradation would reduce range. The unit initially ran remote diagnostics and called customers, but wouldn’t share non-range issues and eventually stopped testing altogether.

The aim was reportedly to both save money (about $1,000 per appointment, according to managers) and reduce strain on service centers already facing long appointment queues. Tesla updated its mobile app to remove appointment options for users asking about range, and instead gave them the choice of asking a company representative to call.

The complaints don’t stem from technical flaws, the insiders claim. Instead, Tesla supposedly began tinkering with range estimates roughly a decade ago to exaggerate figures when an EV was fully charged. Cars would only begin showing more accurate range numbers below a 50 percent charge. The company also gave vehicles a 15-mile range buffer when the estimate reached zero, much as combustion engine cars still have fuel in the tank when the gauge reads “empty.”

It’s not certain if Tesla continues to rely on code to exaggerate range, if the report is accurate. Tesla has disbanded its public relations team and isn’t available for comment. However, the company has already faced criticism and legal trouble over range concerns. The EPA asked Tesla to slightly reduce its range estimates from the 2020 model year onward, and South Korea fined Tesla $2.2 million in January for allegedly failing to disclose that range can drop in cold weather.

Tesla isn’t alone in embellishing range, but may be worse than most. The standards body SAE International recently published a study indicating that EVs typically fall 12.5 percent short of their official range in highway driving. One of the co-authors, Gregory Pannone, tells Reuters that Tesla’s shortfall was a much higher 26 percent. Brands like Ford, Mercedes and Porsche also offer more conservative estimates by using an EPA formula instead of running extra tests. 

Elon Musk’s firm isn’t necessarily cheating, as Pannone explains. Instead, it may be exploiting EPA range procedures more aggressively than its peers. If true, though, that’s still problematic for buyers who might never come close to the range they expected.

Researchers at NYU’s Tandon School of Engineering and Grossman School of Medicine have created an app to help people with visual impairments navigate New York City’s subway system. Commute Booster uses a smartphone camera to recognize relevant signs along a transit route, guiding the user to their destination while ignoring nonessential signs and posters.

Commute Booster is designed for the “middle mile,” where passengers trawl through turnstiles, busy passageways and terminals to stay on the correct route. The app combines general transit feed specification (GTFS), a standardized and publicly available database about public transportation routes, with optical character recognition (OCR) to interpret signs and guide the user accordingly. “By integrating these two components, Commute Booster provides real-time feedback to users regarding the presence or absence of relevant navigation signs within the field of view of their phone camera during their journey,” an NYU press release published today reads.

A study that used the app on three NYC stations — Jay Street-Metrotech, Dekalb Avenue and Canal Street — had a 97 percent success rate in identifying the relevant signs needed to reach a mock destination. It managed to “read” the signs at a distance and from various angles expected from a typical commute.

“The ‘middle mile’ often involves negotiating a complex network of underground corridors, ticket booths and subway platforms. It can be treacherous for people who cannot rely on sight,” said John-Ross Rizzo, MD, an NYU professor (and co-author of the paper) known for his engineering work that helps people with disabilities. “Most GPS-enabled navigation apps address ‘first’ and ‘last’ miles only, so they fall short of meeting the needs of blind or low-vision commuters. Commute Booster is meant to fill that gap.”

Next is a planned human subject study to see how well the app holds up in real-world navigation scenarios. After that, the researchers hope to make it available for public use “in the near term.” Commute Booster is a simple smartphone app using a modern handset’s standard sensors, but that means users need to hold their phones’ cameras up as they navigate New York’s subway system — still well worth it, but less than an ideal setup. One can easily imagine this or a similar app running on AR smartglasses if or when they ever find broader consumer appeal. (Some companies have already tried.)

It’s been two months since The Legend of Zelda: Tears of the Kingdomknocked our socks off, so if you’ve saved Hyrule and are looking for something else to play, Nintendo may have you covered. The company just dropped two classic Zelda titles onto its Nintendo Switch Online platform.

The games include The Legend of Zelda: Oracle of Seasons and The Legend of Zelda: Oracle of Ages, both released for the Game Boy Color way back in 2001. Despite sharing similar names and original release dates, these are separate titles with unique power ups, gimmicks, overworlds, NPCs, dungeons and more, though they do connect in certain spoilery ways.
