Anybody who’s regularly driven in winter conditions knows the importance of keeping windshield washer fluid topped up. Keeping the salty grime stuck to your windshield and rear window to a minimum is crucial for visibility, especially in inclement weather.
In the case of an autonomously operating vehicle, ensuring visibility for the vehicle’s sensors could similarly be a matter of life and death. That’s particularly true for Tesla’s Cybercab ride-hailing vehicles, which rely entirely on camera feeds. Recent sightings of an early prototype in Chicago — a city known for its harsh and long winters — suggest the EV maker is taking the matter seriously, opting to install a rear-facing camera washer to keep obstructions to a minimum.
Images of the salt-covered prototype show liquid — presumably windshield washing liquid or antifreeze — dripping down its rear bumper, almost as if it had a runny nose.
The Cybercab has a rear camera washer!
This is a feature than many Tesla owners have been asking for, especially in snowy areas. Hope it makes it to the rest of the lineup. https://t.co/ufrUvrSnun pic.twitter.com/nueAsqz2YO — Sawyer Merritt (@SawyerMerritt) January 18, 2026
The design change suggests the Elon Musk-led company is taking active measures to ensure its Cybercabs can operate in actual winter outside of its home states of California and Texas.
Tesla is hoping to expand its autonomous Robotaxi system in cities across the country. In November, the company announced that Las Vegas, Phoenix, Dallas, Houston, and Miami are next. Why the cab was spotted in Chicago remains unclear.
However, others lamented the fact that the company’s EV lineup, which has since been seemingly relegated to the bottom of the company’s priority list, had yet to benefit from a similar washer system, despite being on sale for many years now. Rear camera washer systems are a common feature among many production vehicles from other carmakers.
“This is a feature that many Tesla owners have been asking for, especially in snowy areas,” tweeted automotive journalist Sawyer Merritt. “Hope it makes it to the rest of the lineup.”
