Painted optical illusion road blocks trick drivers into slowing down near school zones in India

Speed bumps and zebra crossings aim to slow down road traffic, but that doesn’t mean every driver obeys those kinds of road warnings. That’s why the city of Ahmedabad, India took painted road instructions a step further, and created optical illusions that look like three-dimensional road blocks when approached from the right angle.

A highway management company in Ahmedabad commissioned local artists Saumya Pandya Thakkar and Shakuntala Pandya to paint the optical illusion crosswalks in school zones. “A lot of school kids were crossing the road, and it was not safe for them because of the high speed of the highway,” said Thakkar. Drawing inspiration from similar crosswalk illusions that had been painted in China, the duo painted a total of four highway crosswalks in Ahmedabad’s school zones.

Since completing the project in January, Ahmedabad highway officials have reported that accidents have been eliminated in those four dangerous traffic areas. The illusion is effective because at a distance, drivers’ eyes are tricked into believing there is a three-dimensional roadblock in the middle of the highway. After slowing down on approach, drivers can clearly see that the blockage is an optical illusion as they near the painting, so they don’t brake completely or stop the flow of traffic.

If anything else, getting drivers to pay attention to their speeds in active school zones has had a positive impact. “It’s not that dangerous for the drivers, because they can make out that this is just a painting. But the idea is that they pay attention because of the new creations,” said Thakkar. And for any driver with a sense of humor, the optical illusions might even send them on their day with smiles on their faces.

AI doesn’t have to turn evil to put you at risk

An AI assistant that agrees with everything you say might feel like the perfect companion — until you need someone to tell you you’re wrong. That’s one of the more immediate dangers behind the idea of AI “going rogue.” A chatbot can cause harm without developing intentions of its own. It can reinforce a false belief, encourage an unhealthy attachment, or follow instructions planted by someone trying to hijack it.   

On October 15, AI safety company Alice announced new software to address those everyday risks. Working separately with Inflection AI and AI21, the company says it helped train NVIDIA’s Nemotron models to resist harmful conversational behavior and malicious instructions while preserving their usefulness.

Elon Musk has revealed ambitious plans for Neuralink, and they go beyond controlling computers with your thoughts. The company is developing two brain implants, Telepathy and Blindsight, aimed at helping people with paralysis and severe vision loss. Musk also believes future advances could help people regain control of their hands and legs by reconnecting the brain with their limbs.

Sony has shrunk its glasses-free 3D technology into a tiny screen, and it can bring anime characters to life on your desk
It's almost like having a digital, three-dimensional companion on your desk.
Sony's smaller 3D display for desk

Glasses-free 3D has always felt like a luxury I could admire from afar. Those screens were built for design studios, not smaller desks like mine. But Sony’s new version is small enough to sit beside my keyboard, and I’m genuinely excited.

The company has unveiled the ELF-MN1, a 6-inch display that makes 3D characters and avatars look like they’re coming out of the screen without any special glasses or a headset. It plugs into a phone or PC with one USB-C cable, and that’s pretty much it (via Sony).
