    I agree Marty.
    I can't understand why he's persisted even *this* long!

    be NSW / Vic differences still)

    If the cyclist was not going too fast for the conditions why did he
    collide with the pedestrians? Was he not watching where he was going?

    Yah but to be fair they did retro-fit the earlier C model with one of
    those after market 3 on the floor shifters so it looked like the later one.

    Actually it's closer to kerosine...

    There is (or at least was) a defence specifically relating to
    pedestrians crossing when the pedestrian marker was red in Victoria.

    I'm somewhat familiar with this because I guy I knew hit a person who
    walked out on the red and she died.

    Not up on the details and the guy is now in Darwin, not sure how I'd
    check the court records...

  7. I'm still pretty sure the vehicle has to give way to pedestrians in
    all states. Yes, if someone is crossing a red light then if you hit
    them, a court will exonerate you from manslaughter if it goes that
    far. But the bigger nastier car has to give way to pedestrians as much
    as it is possible. It's not just a legal situation, it's common bloody
    sense. If you do strike a "jaywalker" then you probably won't end up
    in jail. But if you ploughed into a bunch of people on a green
    pedestrian light I think you might have a little while of very bland
    food and a small room.

    I was under the impression it was a bicycle. Whereas 40 is a fairly
    achievable rate of travel on a bicycle, it requires a fit person to
    maintain that speed. I would think 50 would be beyond 95% of cyclists,
    except when riding down a steeep hill. 700? Unlikely. I understood you
    to be crossing the road away from a marked pedestrian crossing, you
    didn't pay appropriate attention, and you probably were partly the
    cause of the cyclist being distracted enough to have a subsequent
    accident. Was the speed limit less than 40 km/h and do you think it
    would have been inappropriate for another vehicle to be travelling at
    or near the posted speed limit?

    I kinda thought Kev just made up the second incident (to demonise the
    cyclist) but for the sake of the argument there could be a few reasons
    other than speed.

    Of course we've already mentioned the most obvious; that the crash was a
    result of him being out of control after having to swerve to avoid Kev.

    He might also have turned his head to give Kev a long withering-stare
    and not looked back in time.

    He may have even just become so angry at meat-head pedestrians that he
    decided to ram the next one he saw!

    The fact that he was turning when he collided with them tends to
    indicate that speed *wasn't* much of a factor (hard to speed around
    right-angle corners on a pushie)

    Yes they should not have crossed the crossing when the lights were green.

    They don't have to leave clearance for the pedalling!

    cornering speed is a function of grip, which is entirely down to the
    coefficient of friction between the tyre and the road, limited by how
    far over you can lean the bike / how far over you can get the centre
    of gravity of the bike/rider combination. You should be able to lean
    a road pushbike on grippy rubber a fair way over, so you should be able
    to get around corners pretty quick. Has almost nothing to do with
    weight, the extra sideways force from momentum is exactly countered
    by the extra grip from the extra mass. Which is why they put wings on
    F1 cars - extra grip without using stickier rubber (that won't last
    as long)

    You go really fast round corners on a pushie by coasting with the inside
    pedal raised to the top - massively more clearance than any motorcycle on
    the planet. Where on earth did you go to school that you didn't learn
    that?

    If you read what Kev actually wrote, rather than what he implied, you'll
    see that nowhere does he say the pedestrian lights were green. If they
    were, since you never have a Walk / Don't Walk without a matching set of
    traffic lights, the cyclist went through a red light.

  15. He was turning from a street with a green light with pedestrians
    having an associated green as well. But I cannot recall whether there
    was a red arrow at the intersection for a right turn. I don't think
    so. But he still has to wait for the pedestrians.

    I'm aware of that but the fact that you can't pedal while hard cornering
    means that you're losing speed (compared to a motorcycle; the example
    Nev was using).

    When they're not pedalling yes.

    I'm guessing that the reason is related to the relative masses of the
    machinery.

    Maybe kinetic energy to friction ratios.

    Psst BT; I think that was Nev's oh-so-subtle point! (in response to the
    "weight's not a factor" post).

    I also think that solar flares might have something to do with it.

    Neutrino emissions and all that.
