Electric vehicles are pretty much inevitable at this point, with carmakers, led by all-EV disruptors such as Tesla, transitioning their respective fleets to electric. Yet despite this, there are still a lot of skeptics who argue that electric vehicles do not really do anything useful for the environment. 

A study from the Keck School of Medicine of the University of Southern California has provided some real-world observations about electric vehicles and how they positively impact the environment. The researchers’ study leveraged publicly available datasets to analyze a “natural experiment” occurring in California as residents transitioned to electric cars. 

The study analyzed data on total zero-emission vehicle (ZEV) registrations, air pollution levels, and asthma-related emergency room visits throughout California from 2013 to 2019. The researchers found that as ZEV adoption rates increased within a particular zip code, the corresponding levels of local air pollution and asthma-related emergency room visits in the areas also decreased.

Erika Garcia, PhD, MPH, an assistant professor of population and public health sciences at the Keck School of Medicine and the study’s lead author, noted that the study shows that changes made at the local level could already improve the health of a community. This is a notable victory for sustainable transportation and the fight against climate change. 

“When we think about the actions related to climate change, often it’s on a global level. But the idea that changes being made at the local level can improve the health of your own community could be a powerful message to the public and to policy makers,” Dr. Garcia said.

The study’s findings were outlined in an Abstract published in the journal Science of the Total Environment. A section of the Abstract can be viewed below. 

“We conducted a zip code-level ecologic study relating changes in annual number of ZEVs (nZEV) per 1000 population from 2013 to 2019 to: (i) annual average monitored nitrogen dioxide (NO2) concentrations and (ii) annual age-adjusted asthma-related emergency department (ED) visit rates, while considering educational attainment. 

“The average nZEV increased from 1.4 per 1000 population in 2013 (standard deviation [SD]: 2.1) to 14.7 per 1000 in 2019 (SD: 14.7). ZEV adoption was considerably slower in zip codes with lower educational attainment (p < 0.0001). A within-zip code increase of 20 ZEVs per 1000 was associated with a − 0.41 ppb change in annual average NO2 (95 % confidence interval [CI]:-1.12, 0.29) in an adjusted model. A within-zip code increase of 20 ZEVs per 1000 population was associated with a 3.2 % decrease in annual age-adjusted rate of asthma-related ED visits (95 % CI:-5.4, −0.9),” the researchers noted in the study’s Abstract. 

The study also showed that there is a significant “adoption gap” in low-resource zip codes when it comes to the adoption of zero-emission vehicles (ZEVs). The research team found that while the number of total ZEVs increased over time in California, the rate of adoption was much slower in low-resource areas. This disparity highlights an opportunity to address environmental justice in communities that are disproportionately impacted by pollution and its associated health issues.

Tesla clears the air on Cybertruck ‘deactivation’ video that is obviously fake

Tesla has cleared the air on the viral video, stating it is fake.

Tesla has cleared the air regarding a video that has been circulating, where the owner claims his Cybertruck was “deactivated” by the company while he was driving.

The video was shared on X and showed a driver pulled over on the side of the road, claiming his Cybertruck had been deactivated by Tesla in the middle of traffic. It is very obviously fake to those who know the company, but these kinds of things have a tendency to pick up steam.

The video shows a screen that says:

“Tesla Cybertruck De-Activated. Critical Issue Detected | Contact Customer Service, Comply with Cease & Desist to Re-Activate. Update Failed, Return to Dealer.”

The same person who posted the video also shared an image of what appears to be a Cease and Desist letter from Tesla, but it is also likely fake:

The company finally responded to the video on Monday afternoon, stating that the video is, in fact, fake, reiterating that it will not disable vehicles remotely for any reason.

It is a shame that these types of things happen, especially as people are prone to believe anything they see on the internet. As there is so much misinformation circulating surrounding Tesla and its CEO Elon Musk, it is no surprise that someone would leverage the situation for their own benefit.

If that Cease and Desist letter is not real, perhaps the next one might be. These types of things can truly cause damage to a company’s reputation, and someone getting an idea that Tesla would remotely deactivate a car could prevent them from buying one.

Elon Musk is stepping up for Tesla Service in a big way

Elon Musk is stepping up to help customers in a big way, especially when they are having issues with Tesla’s Service.

Perhaps one of the biggest advantages Tesla owners have is access to Musk through X, his social media platform. Over the years, we’ve seen Tesla add features, refine its cars’ performance, and more, all through asking Musk directly through a post.

Now, Musk is stepping up in another way by resolving a few Service complaints that customers had.

The first occurred last week when a recall on a Tesla battery was not honored by Service. The company sought $30,000 for a replacement and labor, which was not right. Musk responded that he would personally investigate the matter. The vehicle was fixed at no cost as it was a recall, and was ready for pickup the next day.

It also revealed a new strategy Tesla is using to combat service communication issues:

Tesla creates clever solution to simplify and improve its Service

The next occurred with a Cybertruck owner who was in Japan. Their car was parked at an airport in the U.S. and had lost a vast majority of its state of charge, leaving them just fifty miles of range at the time.

Musk reached out to the owner and said Service will take care of the car and will investigate the cause of the battery drain:

There are not too many companies out there where the CEO will get involved with individual issues like these. It’s pretty exclusive to Tesla, as Musk has commonly stepped up to resolve complaints with vehicles or to confront features that some owners might find useful.

Service has been a weak point of the company for some time, but it has worked to refine and resolve customer complaints by building more Service Centers across the world that can handle these issues.

Tesla CEO Elon Musk confirms Robotaxi is opening to the public: here’s when

Anyone will be able to request a Tesla Robotaxi in September, Elon Musk said this morning.

Tesla CEO Elon Musk has confirmed that the company’s Robotaxi platform is opening to the public, and he even gave a timeline for when anyone will be able to access one for a ride.

Tesla’s Robotaxi platform launched to a small group on June 22 in Austin, Texas. The company has continued to expand the number of riders and its geofence over the past month and a half.

Tesla officially launches Robotaxi service with no driver

Additionally, it launched rides in the Bay Area of California, but it differs slightly, as the Texas Robotaxi platform does not utilize a Safety Monitor in the driver’s seat. In California, the monitor sits in the driver’s seat.

As the geofence, service areas, and testing populations expand, Tesla fans are awaiting their elusive emails that enable their ability to use the Robotaxi platform. It now seems that the email will come soon, as Musk said Tesla will open up public access to Robotaxi next month:

Tesla has been prioritizing safety over anything else with the launch of the Robotaxi platform, which is why it has been slow to push invitations to new riders. It is confident in the abilities of the platform and its Full Self-Driving suite, which has been proven with data.

However, even a single accident could set Tesla back years in terms of its development of self-driving cars. It is not a risk it is willing to take.

Musk said during the recent Q2 Earnings Call:

“We need to make sure it works when the vehicles are fully under our control. It’s kind of one step at a time here. We don’t want to jump the gun. As I said, we’re being paranoid about safety. But I guess next year is I’d say confidently next year. I’m not sure when next year, but confidently next year, people would be able to add or subtract their car to the Tesla, Inc. fleet.”

As the platform will expand in Austin and the Bay Area for anyone, Tesla still continues to reiterate that Robotaxi will be available for everyone sometime next year, as Musk said in the quote above.

Things will continue to improve over time, and Tesla will likely expand its geofence in both regions in the coming weeks. It has already done that in Austin twice, with about a doubling in size occurring both times.
