Waymo Issues Another Recall, This Time Over Highway Construction Zones


Nearly 4,000 Waymo vehicles, the company’s entire fleet of fifth-generation robotaxis, are affected by a new recall issued by the National Highway Traffic Safety Administration related to driving near or within freeway construction zones.

According to an NHTSA report, incidents in Phoenix, Arizona, and San Francisco have raised concerns that autonomous taxis are driving into construction zones to avoid traffic hazards. Those incidents took place in April and May, respectively.

A representative for Waymo didn’t immediately return a request for comment.

The report says that Waymo cars could enter closed construction zones “at speed” because they are incorrectly prioritizing other highway hazards and failing to recognize the construction zones.

The issue affects Waymo vehicles using the fifth generation of the company’s Autonomous Driving System, which would be all of its Jaguar vehicles in service. The company has been rolling out sixth-generation vehicles this year, but they are not listed as part of this recall.

Waymo will remedy the situation by making “software improvements to avoid entering a construction zone and detecting that the AV is within a construction zone, as well as additional operational protocols… The remedy will enhance Waymo AVs performance in and around freeway construction zones,”  according to the NHTSA report.

Previous recalls and issues

While Waymos have become reliable ridesharing fixtures on the streets of cities including Austin, Los Angeles, Atlanta and Orlando, they have also been the subject of some high-profile incidents involving vehicles gone wrong.

In May, a similar recall was issued over the risk of Waymo vehicles driving into flooded areas, posing a safety hazard. Waymos have also been the subject of an investigation related to vehicles driving past stopped school buses and stalling during power outages, as happened last year in San Francisco.

Waymo also drew the attention of Austin’s City Council when a robotaxi blocked emergency response vehicles after a mass shooting in March. A similar incident occurred in Dallas earlier this month when a Waymo robotaxi blocked a road that emergency responders were trying to use after an apartment explosion.

Tesla, Zoox and Uber are other companies that are competing with Waymo in the robotaxi market.

It’s easy to assume that vehicles all had internal combustion engines until very recently. Gasoline and petrol engines were the standard for decades, after all, so why would early vehicles be any different? In reality, the early days of the automobile era were more varied than you might expect, and even featured a range of electric cars. Yes, despite electric vehicles not truly taking off until the 21st century, the first electric vehicles are much older than you think; drivers in the 1900s were going around town in electric vehicles — and where there are EVs, there are charging stations.

One such station, visible in the image above, was the creation of General Electric. Formally called the mercury arc rectifier, it took alternating current and sent it through vaporized mercury in a glass tube. This converted it into direct current, which powered up the EV’s battery. The woman in the image, who’s charging a Columbia Mark 68 Victrola, is standing at the control panel, which allowed a user to adjust power levels. 

These chargers could be installed everywhere, including homes, businesses, and public parking garages, supporting the electric vehicle boom of the early 20th century. While 21st-century EV chargers have come a long way from where they were, the basic building blocks are all still there, and it’s fascinating to see.

How EV chargers have evolved since the early 20th century

EV charging has changed a lot in some ways — but not in others. At the core of it all is the aforementioned conversion from AC to DC, which still happens when you charge modern EVs at standard charging stations. The difference is that your vehicle’s on-board charger performs the conversion, not the charger. Old EV chargers took between several hours and a day to charge, and current-day units can similarly take a few hours to well over a day from empty, depending on the charger’s speed. Fast chargers, which provide DC directly, can cut this down to around an hour or less.

Old-school and modern EV chargers also differ in how they provide power to the vehicle. Mercury arc rectifiers connected directly to the negative terminal of the lead-acid battery that needed charging. Nowadays, EVs use dedicated charging ports. Battery swapping was also commonplace in the early 1900s, and companies like General Electric tried to cash in by offering to replace drivers’ old, run-down batteries with new ones for a fee. That’s not yet possible with most mainstream EVs, although companies like Stellantis have tried to introduce EV battery swapping with moderate success.

Even if they were unrefined compared to today’s models, early EVs seemed to be on to something. Why, then, did electric cars fail, and how did gasoline end up becoming the predominant power source for vehicles?

What led to the downfall of the original wave of electric cars

EVs were no mere fad in the 1900s and 1910s. According to the 1900 United States census, 1,575 of the 4,192 vehicles sold that year were electric, with the value of these early EVs — $2,873,464 — accounting for more than half of the total market value of $4,899,443. It wasn’t just EVs, either; other sources of propulsion, like steam, were also vying for a foothold in the automobile market. By the 1920s and 1930s, though, these had all been superseded by the internal combustion engine.

One of the major drawbacks of early EVs was the fact that electricity was not yet widely available. Electrical hookups were a rarity outside of major cities, limiting the use of these vehicles. The lead-acid batteries they used also had their fair share of issues. They needed to be inspected, cleaned, and repaired every few days, making them more of an inconvenience than anything. Worse yet, they had poor mileage, and, with chargers possibly out of reach, many likely didn’t want to risk being stranded while out for a drive.

Eventually, price reductions for gas cars and improvements such as electric starters and better reliability prompted buyers and automakers alike to move away from electric rides. Thus, while the best-selling EVs of 2026 show that it’s a good time for EVs, this electric boom plainly isn’t the first of its kind. Early EVs eventually fizzled out, but they still set the stage for our current fascination with electric vehicles.
