Winter driving is often a white-knuckle experience, primarily because of the dangers you cannot see. Black ice has a nasty habit of looking exactly like wet pavement right up until the moment your tires lose their grip. However, a team of researchers at the University of Michigan is working on a technological solution that could effectively eliminate that element of surprise for both drivers and pilots. They have developed a new dual-sensor system designed to spot hazardous icy conditions long before a human eye – or even current safety sensors – would notice them. This innovation has already been put through its paces in the sky and is now being adapted for the road, offering a proactive way to prevent the thousands of weather-related accidents that happen every single year.
The first part of the equation is a microwave-based sensor. Unlike the clunky, protruding probes you might see on older aircraft, this sensor is designed to sit flush against the skin of a plane or the body of a car. It works like a sensitive electronic skin, continuously monitoring the surface. By measuring subtle changes in microwave signals, it can detect the exact moment water starts to turn into ice or when buildup begins, providing real-time data without messing up the aerodynamics of a wing.
The second component acts more like a scout. It is a laser-based optical sensor that shoots three distinct beams of infrared light into the air ahead. Its job is to analyze the reflection and absorption of those beams to figure out exactly what is floating in the atmosphere. It can instantly tell the difference between solid ice crystals, which might just bounce off a windshield, and supercooled liquid droplets, which are incredibly dangerous because they freeze instantly upon contact. For a pilot flying into a cloud bank, knowing the difference between a harmless fog and a freezing trap is critical information that currently isn’t easy to get.
On our highways, invisible ice is a factor in nearly twenty percent of all weather-related crashes. It catches drivers completely off guard, leaving them no time to react. In the aviation world, ice accumulation on wings and sensors is linked to roughly ten percent of fatal air carrier accidents because it can ruin the lift a plane needs to stay airborne. The University of Michigan team is trying to close the gap between “thinking it’s safe” and “knowing it’s safe.”
For the average person, this technology could eventually change how our cars behave in the winter. Imagine a future where your vehicle doesn’t just react after you start sliding; instead, it detects the black ice ahead and automatically adjusts your traction control or gently pulses the brakes before you even realize there is a problem. The researchers have already tested these sensors on scientific aircraft with promising results. Now, the focus is shifting to shrinking the tech down and refining it for cars and broader aviation use. If they succeed, this could become a standard feature in the next generation of transport, turning one of nature’s most treacherous hazards into something manageable.
The US National Transportation Safety Board (NTSB) has launched an investigation into Waymo following multiple reports of its self-driving robotaxis illegally passing stopped school buses in Austin, Texas. At least 19 such incidents have been reported since the start of the school year, with Waymo vehicles failing to obey state traffic laws meant to protect children getting on and off buses.
According to Reuters, these incidents occurred even after Waymo recalled more than 3,000 vehicles in December last year to update the software that caused the vehicles to drive past stopped school buses. This reportedly prompted the NTSB to launch its own probe.
In what is one of the most important developments in the Chinese auto industry, Xiaomi’s SU7 has outsold Tesla’s Model 3 in 2025. The information comes from the China Passenger Car Association (via scmp.com).
The Chinese smartphone maker delivered 258,164 units of its first EV. Meanwhile, Tesla sold only 200,361 Model 3s, marking the first time since Tesla’s Chinese launch that another brand has overtaken it in the world’s largest EV market.
The transition to electric vehicles has always had one major stumbling block for car enthusiasts: the sound. Or rather, the lack of it. For decades, the soul of a performance car has been tied to the noise it makes—the intake gasp, the exhaust crackle, the mechanical symphony of pistons and valves. Now, as BMW prepares to launch its first-ever fully electric M3, the company is tackling this problem head-on, and their solution is surprisingly old-school.
Instead of trying to invent a new “sound of the future” filled with abstract spaceship hums and digital warbles, BMW’s Motorsport division is digging into its own history books. New videos from the development team reveal that the upcoming electric M3 will feature a synthetic audio system built from high-fidelity recordings of the brand’s most iconic internal combustion engines. We aren’t talking about generic engine noises here; BMW is literally sampling the legends.
