Last Wednesday, Bloomberg reported that Ford plans to cut up to 8,000 jobs—primarily roles focused on gas-powered vehicles—in order to focus more resources on EV production.

Inflection Point pending.

The rise in popularity of private jet trackers has brought attention to the highest earners’ oversized climate impact. Bloomberg analysis published in March found that the world’s wealthiest emit 70x more carbon dioxide than the bottom 50% combined.

So who are the highest earners?
"The richest 1%— the more than 60 million people earning $109,000 a year—are by far the fastest-growing source of emissions. They live all over the world, with about 37% in the U.S. and more than 4.5% each in Brazil and China."

By all accounts the Zephyr should be dead. There’s no reason the drone should still be flying above the American Southwest after more than a month in the skies. But the Zephyr doesn’t seem ready to die. It’s now been in the air for 47 days. And there’s no indication that the Army intends to bring it down yet.

The Airbus Zephyr S is a high-altitude uncrewed aerial drone, currently undergoing tests in the stratosphere over the Yuma Proving Ground in Arizona. Every hour it sets a new record for the longest uncrewed flight. The Army’s Assured Positioning, Navigation and Timing/Space Cross-Functional Team–the experimentation wing of Army Futures Command–is currently flying the drone in a study on its power system, overall endurance and its capabilities in the stratosphere. The uncrewed flying system is big, at 82 feet in wingspan, but meant to be ultralight, with very little mass to its skeletal frame. It’s powered by a rechargeable battery, which is solar powered, creating a kind of reverse Icarus situation where the more sunlight it gets the more juice the batteries have.

The longer they charge, the harder they fall it seems.

The Zephyr is currently in the air–again, far longer than expected and with no signs of coming down–in its first flight of the year. The current record setting flight has nearly doubled its 2018 record test flight where it stayed in the air for 25 days and 23 hours. The Army’s APNT/Space CFT most recent statement on the tests was on July 21, when the drone had already set a new record.

Now that’s impressive!

Tesla CEO Elon Musk has eliminated use of radar from his systems and relies solely on cameras and computer memory. Brooks and other safety advocates say the lack of radar hurts vision in the darkness.

:mad:
WTF???

What about in the rain??

Yeah... even radar can be rendered useless in the rain at certain frequencies..... point being, we need more (types of) sensors, not less.

I have (not a Tesla) that has some autonomy, but if it rains hard enough, it shuts-down and sends a warning to dash. Don't claim to know all the tech, but has both radar and cameras

Got to drive Sue's '17 Subaru on a long-ish trip over the weekend. The cruise control has a "auto-distance" keeper.... don't know it's real name....
I gotta say, it works a treat. Automatically slows down and keeps pace with the car in front. Left lane clears, pull into that lane and it accelerates back to the "set" speed. All with no "user" intervention. After 10hrs of interstates, I'm impressed.

Like you, I've no idea of the sensor tech involved.

I have to wonder if after enough of these self driving cars are on the road if someone is going to figure out how the cause them to crash? Just one idea I have thought about. Pick a moderate curve in the road maybe with a good drop off. Take a roll of tar paper out and cover up the lines on the road. Car misses the curve and you roll the tar paper back up and leave or maybe see if there is anything in the wrecked car to steal?

Technology has moved on from the basic distance keeper.
My A250e has that facility as part of the Distrionic package.
It match the speed of the car in front when cruise control is engaged, it will slow you down for roundabout's and then accelerate back to the set speed once back on the straight.
With cruise control off, if you are closing on the car in front and you take your foot off the throttle it will also slow you down. You can also set how much gap there is.
RADAR, LIDAR and a lot of clever electronics are probably responsible.

Technology Has Reached a Point Where You Can Own an E-Bike Like the Compact for Just $500​

As technology progresses, something beautiful happens; we are presented with better and better gear for lower and lower prices. That seems to be the case with Hyper's E-Ride Compact e-bike, a little tiny wonder with a big heart. But is that all? Link.

At least quote native English speakers.
