Perhaps more than previous updates, 11.4 focuses on vastly improving vehicle behavior, with new features taking a back seat. According to Tesla’s release notes, those improvements are seen throughout numerous environments.
Foremost, Tesla FSD is better than ever at recognizing and reacting to pedestrians that are either about to cross the street or are already doing so. This stems from an improvement in kinematic calculations, which allows the vehicle to predict where people, vehicles, and objects are going. Regarding pedestrians, the vehicle will act more smoothly, either progressing through the intersection or stopping.
This improvement also extends to other “vulnerable road users,” such as bikers and cyclists, which Tesla FSD will now react more quickly to and slow down for if necessary.
Another improvement that urbanites can enjoy is in “turn performance.” When in dense city areas or unexpected turns, the vehicle will now follow the turn more correctly, dodging parked vehicles and avoiding bus lanes. This improvement is paired with an update to bus lane recognition overall, helping to prevent the vehicle from being where it isn’t supposed to be.
Other updates focus on improving performance in more rural areas. One such improvement is improved lane, line, and edge of road detection, which can be helpful in areas with less consistent road painting and paving. This update feeds into two others, improved lane guidance, ensuring the vehicle is in the correct lane to reach its destination, and improved prediction of the movement of “partial cut-ins,” or cars that haven’t wholly dedicated to a lane. Tesla’s massive library of clips and auto-labeling system makes both upgrades possible.
In the case of improved lane guidance, Tesla states that this update will reduce driver interventions by 64%, ensuring the vehicle isn’t in the wrong lane and reaches the destination more consistently.
Another update affecting how Tesla vehicles behave in lanes is lane change speed control. Tesla FSD will now consider “upcoming navigation deadlines” and will use more or less speed if necessary to switch lanes. Moreover, the vehicle will more accurately calculate the number of lanes it needs to change, thanks to Tesla’s ever-improving vehicle network.
Vehicle speed also improves in countless other situations as well. Thanks to Tesla’s all-new “Vision Speed” network, its network of vehicles can now infer the typical driving speed of any given roadway, improving how the vehicle reacts to areas that typically require lower speeds, such as neighborhoods or parking lots.
The final speed update regards how the vehicle reacts to the weather. The max autopilot speed will now take into account current weather conditions and limit driving speed if visibility or traction is too poor. According to Tesla’s release notes, this calculation is quite advanced, as it will take into account not only its condition, such as tire tread, and its data on visibility and road wetness, but it will also account for outside factors, such as tire spray from other vehicles and traffic intensity.
The final two updates are far more general and will improve the vehicle’s autonomous operation overall. First, Tesla has improved “long-range path blockage,” meaning that its vehicles will more quickly merge into other lanes to avoid obstacles in the road. Second, Tesla has reduced “photon-to-control” latency by 2%, meaning the vehicle will react 2% faster to anything it “sees.”

Tesla robotaxi test details shared in recent report: 300 operators, safety tests, and more
Tesla has launched an initial robotaxi service for its employees in Austin and the San Francisco Bay Area.

During the Q1 2025 earnings call, Tesla executives reiterated the idea that the company will be launching a dedicated robotaxi service using its Full Self Driving (FSD) Unsupervised system this coming June.
A recent report from Insider, citing people reportedly familiar with the matter, has now provided a number of details about the preparations that Tesla has been making as it approaches its June target date.
Remote Operators
As noted by the publication, about 300 test operators have been driving through Austin city streets over the past few months using Teslas equipped with self-driving software. These efforts are reportedly part of “Project Rodeo.” Citing test drivers who are reportedly part of the program, Insider noted that Tesla’s tests involve accumulating critical miles. Test drivers are reportedly assigned to specific test routes, which include “critical” tracks where drivers are encouraged to avoid manual interventions, and “adversarial” tracks, which simulate tricky scenarios.
Tesla has launched an initial robotaxi service for its employees in Austin and the San Francisco Bay Area, though the vehicles only operate in limited areas. The vehicles also use safety drivers for now. However, Tesla has reportedly had discussions about using remote operators as safety drivers when the service goes live for consumers. Some test drivers have been moved into remote operator roles for this purpose, the publication’s sources claimed.
While Tesla is focusing on Austin and San Francisco for now, the company is reportedly also deploying test drivers in other key cities. These include Atlanta, GA, New York, NY, Seattle, WA, and Phoenix, AZ.
Safety Tests
Tesla reportedly held training events with local first responders as part of its preparations for its robotaxi service, Insider claimed, citing documents that it had obtained. As per the publication, Tesla had met with the city’s autonomous vehicle task force, which include members of the Austin Fire Department, back in December.
Back in March, Tesla reportedly participated in about six hours of testing with local first responders, which included members of the fire department and the police, at a close test track. Around 60 drivers and vehicles were reportedly used in the test to simulate real-world traffic scenarios.
Interestingly enough, a spokesperson from the Austin Police Department stated that Tesla did hold a testing day with emergency responders from Austin, Williamson County, as well as the Texas Department of Public Safety.
Reported Deadlines
While Tesla has been pretty open about its robotaxi service launching in Austin this June, the company is reportedly pursuing an aggressive June 1 deadline, at least internally. During meetings with Elon Musk, VP of AI software Ashok Elluswamy’s team reportedly informed the CEO that the company is on track to hit its internal deadline.
One of Insider’s sources, however, noted that the June 1 deadline is more aspirational or motivational. “A June 1 deadline makes a June 30 launch more likely,” the publication’s source noted.

Atty who refused to charge six-time Tesla vandal sparks controversy
Despite the multiple offenses, Moriarty opted to enter Adams into an adult diversion program instead.

Hennepin County Attorney Mary Moriarty, who made the decision not to charge 33-year-old vandal Dylan Bryan Adams after he keyed six Teslas around Minneapolis last month, has found herself in the middle of controversy.
The controversy came amidst her decision to press charges against a 19-year-old first-time vandal who keyed one vehicle at the White Castle in Brooklyn Park.
The Tesla Vandal
Moriarty’s decision not to charge Adams after he keyed six Teslas was met with widespread criticism. Adams’ actions resulted in more than $20,000 worth of damages, more than $10,000 of which was to a single vehicle, as noted in a New York Post report. Yet despite the multiple offenses, Moriarty opted to enter Adams into an adult diversion program instead.
The fact that Adams is a state employee who works for the Department of Human Services as a program consultant triggered allegations that his dismissal might be partly influenced by Gov. Tim Walz. Walz is a staunch critic of Musk, previously stating that the falling price of TSLA stock gives him a “boost” in the morning.
As noted in a report from The Minnesota Star Tribune, Moriarty’s decision was so controversial that she was asked about the matter on Wednesday. In response, the attorney argued that her office made the decision outside of any political consideration. “We try to make decisions without really looking at the political consequences. Can we always predict how a story will be portrayed in the media or what people will say? No,” Moriarty stated.
Actually Charged
As noted by the Tribune, Moriarty has made arguments around the fact that Adams was a first-time offender, even if he opted to deface six separate Teslas. But even this argument has become controversial since Moriarty recently charged a 19-year-old Robbinsdale woman with no criminal record with first-degree felony property damage after she allegedly keyed a co-worker’s car. The damage incurred by the 19-year-old woman was $7,000, substantially less than the over $20,000 damage that Adams’ actions have caused.
Cases surrounding felony first-degree property damage are fairly common, though they require the damage to be over $1,000. The 19-year-old’s damage to her co-worker’s car met this threshold. Adams’ damage to the six Teslas he vandalized also met this requirement.
When Moriarty was asked about her seemingly conflicting decisions, she noted that her office’s primary goal was to hold the person accountable for keying the vehicle and get restitution to the people affected. She also noted that her office tries to avoid convictions when possible since they could affect a person’s life. “Should we have treated this gentleman differently because it’s a political issue? We made this decision because it is in the best interest of public safety,” she noted.

Tesla faces emission credits tax in Washington state
House Bill 2077 taxes emissions credits, mainly hitting Tesla. Lawmakers expect $100M/year from the taxes.

Washington state lawmakers are advancing a bill that would tax Tesla’s emission credits, targeting profits under the state’s clean vehicle policy. Lawmakers who support the bill clarify that the Tesla credit tax is unrelated to Elon Musk.
HB 2077, introduced in mid-April, seeks to impose a 2% tax on emission credit sales and a 10% tax on banked credits. The bill primarily affects Tesla due to exemptions for companies with fewer credits.
In 2022, Washington’s Department of Ecology mandated that all new cars sold by 2035 be electric, hydrogen-fueled, or hybrids, with 35% compliance required by next year. Carmakers selling more gas-powered vehicles can buy credits from companies like Tesla, which sells only electric vehicles.
A legislative fiscal analysis projects taxes on those credits would generate $78 million in the 2025-27 biennium and $100 million annually thereafter. About 70% of the taxes will be allocated to the state’s general funds, and the rest will help expand electric car infrastructure.
HB 2077 passed the state House eight days after its introduction and awaits a Senate Ways and Means Committee vote on Friday. At a House Finance Committee hearing, supporters, including union and social service advocates, argued the tax would prevent cuts to state services.
House Majority Leader Joe Fitzgibbon emphasized its necessity amid frozen federal EV infrastructure funds. “We didn’t have a budget crisis until this year. And we didn’t have the federal government revoking huge amounts of federal dollars for EV infrastructure,” he said.
Tesla’s lobbyist, Jeff Gombosky, countered that the proposal “runs counter to the intent” of the state’s zero-emission policy. Rivian’s lobbyist, Troy Nichols, noted a “modest” impact on his company but warned it could undermine the EV mandate. Kate White Tudor of the Natural Resources Defense Council expressed concerns, stating, “We worry it sets a dubious precedent.”
Fitzgibbon defended the tax, noting Tesla’s dominant credit stockpile makes it “one outlier” that is “very profitable.” “That’s the kind of thing legislators take an interest in,” he said. “Is it serving the interest of the public for this asset to be untaxed?”
With the legislative session nearing its end, the bill remains a key focus in budget talks in Washington.
