They absolutely do not support this in any meaningful way. Try telling them they have to get rid of their car and stop flying, and that in the meantime gas prices will shoot upwards, and then let’s see how much they actually support this. They just said they supported it in a poll either because they thought that’s what they were meant to say, or because they didn’t understand the implications of what they were agreeing to

Contrary to what somebody else has said here, this IS potentially extremely useful as it paves the way for real-time aerodynamic calculations when paired with power data. mywindsock is the go-to resource for this, but briefly, with wind data your head unit could quite easily calculate real-time CDA, and as a result pretty much make the advantages of wind tunnel testing available to all of us - plus give instant feedback mid-ride on how well we’re holding a good aero position.

In short, this device could be a game-changer and I suspect every pro will have one almost immediately

Just to be clear, this is capitulation to a car industry that failed to modernise fast enough and now is crying out for protection from Chinese competition while they belatedly get on with some R&D

If you read the paper, they’re building on existing work that shows night-time light affects the metabolism

Sorry, but no

If they really cared about children and the most vulnerable they’d be taking much firmer action about car pollution, especially near schools and hospitals

Thanks!

Thank you - that’s a really useful answer. I’ll check them out

Thank you - I’ll have a look at that

It feels like Twitter did 12 years ago - in my experience it’s a really engaged place with high-quality conversations. It really highlights how far Twitter has fallen, and after the last couple of years on Twitter I had to re-learn how to have civil conversations with people who are acting in good faith, because I’d grown so unused to that

Any vaguely recent car is constantly reporting its location back to its manufacturer.

I’m guessing that’s Venus

I’d be very intrigued in a system that lets me leave my phone in my (waterproof) pocket and access audio and navigation on Bluetooth. Let’s get this on bikes asap

One of my big worries with the way people are using LLMs is that they’re being trained to trust whatever they spit out. Hey Google, what’s the nutritional content of peanuts? And people are learning not to ask where the information came from or to check sources.

One of the many reasons this worries me is that very soon these businesses are going to need to recoup the billions they’re spending, and I wonder how long until these systems start feeding paid promotions to a population that’s been trained to accept whatever they’re told. imagine what some businesses, or governments, would pay to have exactly their choice of words produced on demand in response to knowledge queries.

Interestingly, my family subscription more or less halved a few months ago, which I was NOT expecting, but which was very welcome

This is greenwashing. Global aviation uses almost 100 billion gallons of fuel per year. If we even began to address a fraction of that with magic new fuels (which won’t happen) it would require incredible amounts of growing, and if we had that sort of amount of agricultural capacity available on this planet, capable of producing crops at a price the aviation industry is prepared to pay, we wouldn’t have any hunger on the world.

Don’t fall for this. There isn’t such a thing as green aviation. I’m not saying there should be no flying, but we can’t carry on as we are and magic away the consequences. In particular, don’t fall for the snake oil salesmen trying to distract you with appealing non-solutions

Hard to get too excited when Norway funds all this by selling fossil fuels

It would have a massive effect. Transport (car) emissions are one of the larger - and growing - sources of emissions.

And we can’t hide behind “But the corporations…” because ultimately what they produce gets used by us.

So to answer your question: riding a bike when Global Capital wants you to keep buying cars and pumping oil into them is one of the best acts of defiance you can make

If it’s a tiny bit of comfort, you probably don’t need a new derailleur, just a new cassette with the right spacing. The mech itself will likely work with different cable-pull, as long as you’re not drastically changing the number of sprockets on the cassette
