    I saw her pre-departure news interview. And give me a cite where I said that making nylon rope generates more carbon per passenger km than flying. Yow can't....

    #609 and #611 - I'm saying that the carbon cost per hour of running a racing yacht with a carbon fibre mast, nylon or polypropylene sails, and nylon rope rigging is not 0, as she appears to believe. That sort...

    #595 - I'd not heard the trailer hitch bit before. What I had heard (from EV vested interests) summarises as "but the battery's not mine. What if mine gets replaced with a duff one here?" #596 - Yes and no....

    I re-read this, and it occurred to me that "zero waste" requires, for example:- 1) banning the sale of print publications, because paper can't be recycled indefinitely or readily composted. 2) banning toilet paper because it is use once and...

    Greg has recently (late 22nd or today) posted the latest TRRL report on the subject (management summary "it's really complicated, no, more complicated than that"), but the fourth power of axle weight law does come into it. So it honestly...

    Well, "Cyclicious" is, not entirely unexpectedly, just another pro-cycling, "we shouldn't pay road maintenance because we don't cause track damage" blog. Not all damage to sealed surfaces is a result of vehicle pressure guys! If you want a dedicated lane...
  • Commented on Upcoming events
    Well, thank you for summarising several posts I already made. ;-) And indeed, for re-writing the one you quoted to prove that someone else understood it....
  • Commented on Upcoming events
    Agreed; the 4th power law in question originates from an respectable source in the TRRL, but no-one has ever felt the need to state it in full (OK, the TRRL will have a report with it in full, but without...
  • Commented on Upcoming events
    Cheers; I've just plain never seen any full statement of the law linking axle weight to road damage. I have seen various explanations of lifting undriven axles, but they all boil down to reducing tyre, brake and bearing wear on...

    Website seems to work fine for me, at least to the point where I've discovered that a "Arcimoto Evergreen" weighs 1_800lb, and a Morgan 3 wheeler a little under 1_200lb (both manufacturer figures). Neither seems to come with the full...

    Don, I think you may be talking slightly at cross-purposes with EC here. I think he is referring to the KE stored in a moving vehicle, which, simplifying to Newtonian dynamics, is E = 0.5mV^2, at least in the post...

    Well, my point was that XR UK are actually creating logically found resistance to their actions by those very actions. Were they to block London's surface streets by supergluing themselves to buses instead... As for Greta's stunt, I heard her...

    #513 - I also hang out at work, and on car enthusiastic sites.There, the general view of so called "XR UK" is that they may have a point but their methods are wrong, largely because they are causing more pollution...
  • Commented on Upcoming events
    Indeed; modern motorcycling gear is sometimes called armour, and often consists of Kevlar plates inside a leather garment....
  • Commented on Upcoming events
    Para the last. - Agreed. Additional note that the automated announce has been named "Sonya" on Scotrail, because she has a voice that getS ON YA nerves....

    You say "mobility scooter"; I think "go-kart with a dining chair on top". See why it's unstable at speed? Compare it with https://www.renault.co.uk/vehicles/new-vehicles/twizy.html?utm_source=Bing&utm_medium=cpc&utm_campaign=Local-All-bi-UK-P-Defensive-TWIZY-RLSA-Exact&utm_term=renault+twizy&ORIGIN=CPC&CAMPAIGN=bing_Local-All-bi-UK-P-Defensive-TWIZY-RLSA-Exact&msclkid=05ae105b2a231e7d9e6d4d0640623d91&gclid=CIv3w7qqlOQCFQSIGwodUQ4JzA&gclsrc=ds which I think has crosswind issues, although I would have to use it in a full gale...

    #483 - All "not being caught speeding" (or being a mobile chicane either) requires is sufficient speed awareness to be around up to typical local speed and below the 90th percentile speed. I don't think that's a sufficiently big ask...
  • Commented on Upcoming events
    Someone clearly did not follow correct procedures in coupling and brake testing. The driver followed correct procedures for a brake failure and no-one was (seriously) hurt. Accordingly the correct thing to do seems to be to wait for the RAIB...
  • Commented on Upcoming events
    #467 - That just makes me think you're a poor driver. I've never had a speeding ticket and am only rarely pinged by "you are speeding, slow down" sensors. The only "cruise control" I've ever had is conveniently attached to...

    Not quite; modern trucks use air (release) actuation on the wheel brakes on every axle. Also https://en.wikipedia.org/wiki/Retarder_(mechanical_engineering) - In European parlance an eddy current brake is often known as a "Telma" after the leading supplier....

    Other, already existing, trucks include the "tridem". This has a steer axle under the cab (and engine), then at the back end, in the sort of spacing you're probably used to seeing on semi-trailers, a steering axle, the drive axle,...
  • Commented on Upcoming events
    6 axle articulated trucks are not uncommon in the UK (more axles are reasonably common in Scandinavia, Australia* and North America). You're only partially addressing the problem though, because you need to look at the mass on the heaviest loaded...

    I can't afford a new car at £16_000 either. The most I have ever actually spent on a car purchase is about half that....
  • Commented on Upcoming events
    You might like to tell me where the ~£39_000 between the value of my present car and the sticker of a Tesla is coming from? How about why you believe that the present favourable tax position of EVs, which pay...

    My idea of using the coders' project managers as crash test dummies was to make sure the PMs' minds were concentrated on "the very best we can do" rather than "writing and testing down to a price". I'm not looking...

    Make up your mind. You started with a figure for road traffic deaths; you posted it so don't even think of denying it! Now you're trying to conflate that with things like particulates (there is work that shows that, unless...
  • Commented on Upcoming events
    OK, first show that electric cars will directly kill fewer people per year. Then, and only then, you may have a point....
  • Commented on Whoops Apocalypse!
    Now it's been leaked it's not an issue beyond that I couldn't deep link it. If the leaker's name was known, they could be in trouble but there's no issue with quoting something that's already in the press (well beyond...
  • Commented on Upcoming events
    I know you're Australian, but you might want to watch a documentary on nickel mining in Canada, and check some of the nastier failure modes of lithium ion batteries before claiming that battery electric cars actually solve problems....
  • Commented on Upcoming events
    Well, I have a simple test for self-driving vehicles. Are the project managers responsible for the teams developing the code prepared to put themselves, literally and physically, in front of a vehicle doing 50mph, pass criteria being that they are...
