Gareth Dennis, a commentator on the social media platform X and a rail engineer, expressed concerns regarding the implementation of Waymo-style robotaxis in Florida’s storm-prone market. He said that these autonomous vehicles, which still require remote assistance in abnormal situations and may pause service during adverse weather conditions, should not be the foundation of a driverless-only network in such an environment.
“Yes, and still remote operated in most “abnormal” situations,” said Dennis. “Still unable to run in inclement weather. Still on some of the easiest road conditions imaginable.”
Waymo has outlined its “fleet response” program, where remote agents monitor camera feeds to provide guidance when vehicles face unusual roadworks or emergency scenes. Despite this assistance, the software maintains formal control of the car. Dennis’s comments reflect broader questions about whether a system reliant on remote assistance and avoiding challenging environments is ready to replace human drivers entirely in markets like Florida.
Research indicates that adverse weather conditions such as heavy rain and fog can impair autonomous vehicle sensors, increasing risks and potentially causing slowdowns or shutdowns. While Waymo asserts that its Driver can operate under challenging conditions, it acknowledges that severe weather may necessitate slowing down, rerouting, pulling over, or briefly pausing service. In September 2025, heavy rain and flash flooding in metro Phoenix led Waymo to suspend robotaxi operations temporarily due to flooded streets and stalled cars.
Florida law permits fully autonomous vehicles on public roads without a human operator physically present. The automated driving system is recognized as the legal driver for on-demand networks authorized by CS/HB 311. However, Florida’s climate poses challenges with its average annual rainfall of 40–60 inches and frequent thunderstorms. Critics argue that relying solely on driverless networks could leave users stranded during storms when services are paused.
Dennis is a UK railway engineer who contributes to rail and transport policy debates and lectures on railway systems. He hosts the weekly “Railnatter” show and has authored a book advocating for sustainable transport solutions through railways. X Corp., which operates the platform where Dennis shared his views, aims to serve public conversation by providing a real-time forum for news and policy discussion.
