  • In a car with ABS, two sets of tyres with different grip will have a different point at which tyres lock up, with grippier tires locking up later and ABS letting the brakes bite harder before acting.

    Now a harder question is whether a tyre with less rolling resistance will be less grippy. All things equal, yes, it will. Tyres grip by deforming and creating friction in the contact patch, and the point of these tyres is to reduce friction.

    To make up for this, manufacturers use clever designs (e.g. where tyres can deform more under certain conditions) so that they can retain characteristics similar to tyres with more rolling resistance. Of course, everything in engineering is a compromise, which means that A) these tyres are more expensive because of the additional complexity and B) the design and materials science can only go so far and they have indeed slightly less grip; otherwise all the tyres would be like this.

    As an anecdote, Toyota sold the GR86 with Michelin Energy Saver tyres fitted as standard (in Europe at least) for “grip” reasons: they allowed the car to drift at really low speeds (some car journalists commented that it was remarkably easy to take roundabouts sideways at legal speeds).





  • This is one of the rare things where the Spanish left and right agree, for different reasons.

    Simplifying a lot:

    • The left generally supports culture, actors, theatre, writers, Spanish made movies. They see piracy as a threat to the earnings of those people.
    • The right has historically cut any sorts of subsidies to the “culture creators”, but they see piracy as a threat to the publishing, TV (…) industries.

    They both support SGAE, which translates cleanly to the General Society of Authors and Editors, who protects their interests by charging fees to everyone who dares look at copyrighted work.

    • You own a bar and you play TV, Radio, or Spotify? You have to pay SGAE.
    • You buy a computer, part of the money goes to SGAE.
    • You buy a blank CD, DVD, Hard Drive, you pay SGAE (because they know you will put copyrighted material there, and if you don’t, well, fuck you)

    It’s a fucked up system and I don’t know if things have changed in the past few years as I don’t live in Spain anymore. But it honestly feels like a prosecution of the population who is so evil and trying to destroy Spanish Culture.


  • The UK measures alcohol in units to track total amount consumption, as it’s not easy to track with percentage in volume. A unit is 10 ml of pure alcohol, and cans/bottles/etc have the total units printed. That way it’s supposed to be easier to track how much alcohol you drink e.g. if you drink a beer, then a wine - now that’s 4 units.

    I’m not British so I’m not used to units, but at least that’s the theory.


  • I always thought it was because 440ml is a round number when you convert it from metric to medieval units (not a pint though, which is 568ml), but a quick google shows me there’s another reason:

    One reason for the popularity of the 440ml size is its convenience for calculating alcohol units. A 440ml can at 4.5% alcohol by volume (ABV) equates to exactly 2 units of alcohol, making it easier for consumers to track their alcohol consumption
