Tesla Motors, the all-electric vehicle manufacturer, is known for building popular EVs such as the Model 3, Model S, and upcoming Cybertruck. Tesla says it is developing the hardware and software necessary to power the world’s first self-driving cars. This software costs Tesla owners an additional $8,000 to purchase what it calls the Full Self-Driving Capability suite of features. But do all the features of the Full Self-Driving Capability package work as promised? We explain each feature’s intended use, and show you how they performed in our tests.

UPDATE: After publishing this video, a viewer alerted CR that there was a mismatch at 5:50 between what we described happened with stop sign control–our tester slamming on the brakes after the car missed the stop sign– and what we showed onscreen–the car slamming on the brakes. CR’s testers did experience both scenarios.

A Tesla Model 3 from China has recently gone where no other Model 3 has gone before. In an epic 5,500 km (3,400-mile) road trip, a white Tesla Model 3 Dual Motor AWD started a long journey from Shenzhen all the way to the base camp of Mt. Everest. What’s more remarkable was that over the long trip, the Tesla owner remarked that he experienced no range anxiety at all, despite his extremely remote destination.

Driving to the base camp of Mt. Everest is no joke, and it is hardly something that is considered relaxing and convenient. Needless to say, any trip that involves one of the highest and most dangerous mountains in the world is not something that is taken lightly. Some who drive to Everest’s base camp even utilize support vehicles just to be on the safe side. The Model 3 owner, for his part, took on the journey alone.

Extremely energy-efficient artificial intelligence is now closer to reality after a study by UCL researchers found a way to improve the accuracy of a brain-inspired computing system.

The system, which uses memristors to create artificial neural networks, is at least 1,000 times more energy efficient than conventional transistor-based AI hardware, but has until now been more prone to error.

Existing AI is extremely energy-intensive — training one AI model can generate 284 tonnes of carbon dioxide, equivalent to the lifetime emissions of five cars. Replacing the transistors that make up all digital devices with memristors, a novel electronic device first built in 2008, could reduce this to a fraction of a tonne of carbon dioxide — equivalent to emissions generated in an afternoon’s drive.

In industry speak, he said it has to have electrical Vertical Take Off and Landing (eVTOL) to be a flying car. According to the Deloitte website, eVTOL vehicles have the potential to improve the future of elevated mobility by moving people and cargo more quickly, quietly, and cost-effectively than traditional helicopters. A separate journal described eVTOL as a new means of transport that can fly like an aircraft and take off and land vertically like a helicopter, “sometimes called personal aerial vehicle.”

Yoeli’s company has two models: the CityHawk and the Falcon XP, both of which weigh more than a ton, not including the passengers.

So how did he get these cars to fly?

The FBI is conducting a probe after a pilot from American Airlines reported a man flying a jetpack above Los Angeles International Airport Sunday night.

“The FBI is aware of the reports by pilots on Sunday and is working to determine what occurred,” a spokesperson told FOX 11 Tuesday.

A second pilot from a separate airline company also reportedly spotted a man using a jetpack as the planes were approaching the airport at around 3,000 feet and 10 miles out for a landing.

This is the first time the e-commerce giant has registered a craft directly, rather than leasing it.

Batteries with high energy densities could enable the creation of a wider range of electric vehicles, including flying vehicles that can transport humans in urban environments. Past studies predict that to support the operation of vehicles capable of take-off and landing, batteries require energy densities of approximately 400 Wh kg^-1 at the cell level, which is approximately 30% higher than the energy density of most existing lithium-ion (Li-ion) cells.

In addition to powering flying vehicles, high-energy cells (i.e., single units within a battery that convert chemical into electrical energy) could increase the distance that electric cars can travel before they need to be charged again. They may also reduce overall fabrication costs for electric vehicles, as similar results could be achieved using fewer but better-performing cells.

Anode-free lithium metal cells are particularly promising for creating batteries with higher energy densities. While they use the same cathode as Li-ion cells, these cells store energy via an electroplated lithium metal instead of a graphite host, and they can have energy densities that are 60% greater than those of Li-ion cells.
