Live blog: Video of little girl giving safe overtake lorry driver thumbs-up goes viral, London Quietways under fire after latest death + more

@chrisonabike I think we probably do need a finer grained approach than power-of-ten speed limits, unless you're going to allow for fractional powers, which is going to put an excessive cognitive load on the poor old drivers...

Were you always missing the first period?

@Rendel Harris indeed, but giving this a sympathetic reading it *is* a bit harder to see cyclists especially in low light conditions. I think this usually means "I was a bit startled when I noticed cyclists where not expecting them / so late that if I had needed to I wouldn't have had time for evasive action". That might be when unlit non-reflective cyclists appear from a side road - or where people are salmoning against traffic flow / on and off the footway. We all have tons of experience looking for motor vehicles and are familiar with where they'll be and how they will move. Cyclists are significantly smaller, have more complicated shapes and may not be exactly "where we expect the motor vehicles". They may be moving at unexpected velocities. Plus even if cars don't have their lights on they tend to reflect. I put this one in the "follow the opposite philosophy to 'shared space' for better safety" category. That is: safety between road users is enhanced when a) people can clearly see other road users b) and have as much time as possible to deal with them c) and know exactly where to expect them / what to expect from those other road users. Most humans perform very poorly when faced with the unfamiliar and worse when startled...

@ajuk.uk@gmail.com "There does seem to be evidence that 20 mph limits work on roads that already lend themselves to such low speeds, and I do think the lack of a 25 mph limit option is an issue for some roads." Again - not disagreeing that numbers alone are not the best way. But I ask: were people already doing 20mph or near that when those roads that "lend themselves" to that speed had a 30mph sign? I would expect in most cases the answer was "no, people saw thirty and that primed them for the 'expected' speed". Or perhaps "they hadn't noticed the signs at all but it seemed like e.g. a residential area and they recalled from all those years back 30mph probably made sense"? Since we've previously gone through the evidence * that merely changing a number on a sign *does* in fact change behaviour and lower average speeds, and AFAICS nobody has proposed a "a set amount" they hope it will constrain people to ... ... is it fair you're disputing the evidence because it doesn't fit with how you feel it *should* work / your local experience? Or do you believe that eventually everyone will revert back to the old speed or higher because 'freedom' or because nobody's actually getting nicked for ignoring the limit? (And if the latter - what's the point of proposing that the speed limits should help with policing, if there aren't the police?) While I can believe that the truly reckless and *some* less circumspect wrong'uns are more likely also to wildly speed, I think this assertion needs more scrutiny **. As for "forcing the police to target them" I think it's been amply illustrated on this site that many of the police don't feel forced into doing much if any enforcement on the roads (see wtjs etc.). Even where they are more active the level of enforcement isn't such to make many drivers worry about "what happens if I break the law *and* get caught?" I don't feel we need 25 or 32 or other intermediate speed limits. In practice where there's enforcement at all there *may* be the discretionary 10% + a few mph in play - so you might even be fine and not fined doing 35mph in a 30mph limit. But you're far more likely simply not to experience any enforcement. And even if you are detected it's still first chance, then maybe any number of 2nd, 3rd etc. with a reasonable lawyer / sympathetic magistrate. Although if you feel the most important thing is to identify indifferent drivers (and assuming we've got enough police / cameras / "spy in the car" black boxes from somewhere) then having lots of non-power-of-ten speed limit signs might be a way to spot who's paying attention or not. Or ... if we changed to km/h (imagine!) you get a finer-grained 10 / 20 / 30 etc. * The last time this topic came up, or the time before! ** I don't know if anyone has studied this, but I'm not sure of the relative amounts of harm caused by a) a small minority of reckless joyriders and "sod getting a licence" types (who *are* very likely to cause serious harm) and b) vastly more "average reasonable drivers" - who are human and thus cut corners and sometimes make unfathomable errors - who cause damage (up to killing people and destroying buildings) at a small but definitely non-zero rate overall. It wouldn't surprise me if the overall determinant of harm turned out to be simply proportional to the number of drivers times time driven for times some measure of speed. (Since speed reduces both time to do something about a situation and increases the harm, absent a lot of engineering to mitigate it - e.g. evidence shows motorways are statistically safe environments).

Now the wands are gone, I look forward to the cycling lanes being cleaned regularly - and not parked in (thereby leaving plenty of room for the buses and emergency vehicles) (all to delivered before Coventry win the FA cup again)

@perce everyone should wear lights, full stop. And punctuate properly - that really gets up my colon! Anyway, must dash...

@Ojisan My old English teacher told me i had to work on my punctuation, so I started going to school half an hour earlier.

Arrogant obnoxious Tory.

How do you see them then? Do you regularly drive into black cars?

@Blackthorne83 He'd love to, but some bastard's taken out the cycle lanes.
