Tesla's market share in Europe is collapsing: from 2.8% last February to 1.8% this February, even though EVs are growing. But we need to keep pushing. It needs to be near zero.

Tesla's February market share in Europe drops despite EV pickup
Tesla's market share in Europe continued to shrink year-on-year in February, data showed on Tuesday, as sales of the all-electric car maker dropped for a second consecutive month despite rising overall EV registrations on the continent.

I don't know if all of this is true. I'm not taking it at face value, BUT the concern is real and it's not completely out of the realm of possibilities
You just do not go to the USA at this point, period. At least if you're bold enough to have negative opinions about Trump and his administration (like around 3/4 of all Europeans). It's becoming like a trip to Russia at this point - you can't rule out you'll be jailed in some creepy power play.
French researcher, going to a conference in Houston, was forbidden entry to US; his work and personal electronics were both confiscated.

Why? Because a “random search” of his cell phone revealed a negative personal opinion on Trump and the Trump administration. www.lemonde.fr/internationa...

I’ve posted a detailed explanation of why the claimed ESP32 Bluetooth chip “backdoor” is not a backdoor. It’s just a poor security practice, which is found in other Bluetooth chips by vendors like Broadcom, Cypress, and Texas Instruments too. https://darkmentor.com/blog/esp32_non-backdoor/
The ESP32 "backdoor" that wasn't | Dark Mentor LLC
4 day class covering the full Bluetooth Low Energy (BLE) protocol stack from the bottom (PHY) up to the top (GATT). The core of the class is built around playing with a game application on an Android phone, talking via Bluetooth to an IoT-type piece of hardware, and analyzing the communication between them. The 4th day is focused on assessing a cutomized Ultra-Vulnerable Peripheral firmware, running on Zephyr RTOS, which has had vulnerabilities introduced into it which are representative of vulnerabilities found in the past across many other platforms.

CJ is an old friend and a longtime cDc NSF member. He suffered a fall and broke his neck -- his insurance refused to pay for an MRI, which led to the break going undiagnosed for a couple of weeks, until his vertebrae had degraded to the point of quadriplegia.
