Wemo Releases Software Update for Robo-Taxis Stuck at Traffic Signals During Power Outages

Wemo’s software treats powerless traffic lights as four-way stop signs. However, in reality, many robo-taxis sent a “confirmation check” to Wemo’s fleet response team before moving, causing traffic jams when outages affected large areas simultaneously.

The update will include regional blackout information, improved decision-making algorithms, and updated emergency response protocols. Wemo stated that despite the videos circulating online, its vehicles successfully crossed over 7,000 non-functional traffic signals during the blackout.

Experts say such incidents highlight that even advanced autonomous technology faces real-world challenges. Previous updates were also required for school bus interactions, which had drawn attention from US national road safety authorities.
