Na druhou stranu coby liberální volič jsem zvyklej volit rozumem klidně zcela proti svým zájmům, pokud to znamená možnost za 4 roky volit znovu. Spousta voličů ODS toto nezná, tak se snáz dostanou do mindsetu typu "ODS letos nemůžu, stan dozimetr, piráti komouši, tak prostě volit nebudu".

EVs beat petrol cars on lifetime emissions — even on “dirty” grids.
Battery production is carbon-intensive, but EVs quickly repay that debt and end up 21–71% cleaner over 250,000 km.
We can’t wait for perfect grids: electrify transport and clean the grid now.

As the last 4 years have shown, there are few things more dangerous than a technology which does not exist but is being sold on the premise that it does. Imagine how dangerous it would be to have a machine that people believe reads thoughts but does not. Imagine what law enforcement would do with it

"School officials in the McKinney Independent School District [in Texas] declined to discontinue using the device even after it was banned, saying that they hoped it would be a deterrent: 'We're not looking to nail a particular kid. We're looking to send a message.'[10]"
This is the Quadro Tracker, a machine that was sold to cops and the military as a bomb/drug/contraband detector that worked by taking a picture of the thing you wanted it to find, inserting that picture into a slot, and then waving a divining rod around

![The FBI commissioned the FBI Laboratory's technicians and Sandia National Laboratories to examine the device. They found that the Quadro Tracker contained no electronics whatsoever. It was merely an empty plastic box in which the only metal parts were a couple of wires and the antenna, which were not connected to each other. The antenna was merely a transistor radio aerial.[4] Attorneys for Quadro Corp. later contended that the inductors and oscillators supposed to be inside the device "aren't the type usually thought of by electronics experts".[6] The "locator chip" was shown to be equally fake; one example put on display by the FBI contained dead ants that had been frozen and stuck onto paper with epoxy glue.[4]](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:wfy4l5sl22lgb2lakf6kwqvw/bafkreifppvwls7shwcthyiri7vnzj2ljarq3ug7mf4snpp3iflw3qcctne@jpeg)

Despite the fact that the academic council recommended against it, despite the fact that the program brought in more tuition than it cost, and despite the fact that Nebraskans need & deserve this expertise, Earth & Atmospheric Sciences will be cut.

one of many parallels between anti-vaxxers & those who oppose gender-affirming care: they start by pretending they have a very specific concern (MMR vaccine, puberty blockers, etc), but once given any sway or say on the matter, they quickly strive to eliminate all of it
Kennedy's zombie ACIP panel just voted to restrict hepatitis B vaccine for newborns. Experts say it will harm children for no reason. www.ms.now/news/rfk-cdc...

Technology is cool and all but did you ever happen to think that what is possibly the most impressive and comprehensive transit signal priority system in the world, Zurich's, is essentially based on updated versions of 1970s and 80s tech, i.e. induction loops, antennas and basic programming?
