Are you referring to blow pipes?

Was your riding exactly the same no matter the bike?

I know mine isn't....

Data is the problem. THe MCC of NSW was finally able to get access to
crash reports to try and get some idea of what kind of bike and rider
was having what kind of crash, but the data itself is spotty.

You have people who know nothing about bikes having to put make and
model, and that isn't very reliable. If the make and model isn't clear
on the bike, they'll guess or ignore. Sometimes you might get
"dirt bike" but if it's a road bike they might just say "large bike"
and that could be a Wing, an Electraglide, or a CB900RR. There's a
lot of noise in the data. (And that's not even touching the whole
"cause of crash" problem...)

Then it's a matter of working out what the data might mean. You don't
get young riders on cruisers, but do you get older riders using their
bikes in the city as much? Is the reason most cruiser crashes seem to
be single vehicle because older riders have more traffic smarts, or
because most cruiser riders are using them as recreational vehicles
and aren't riding in the city? Time of crash is an obvious help, but
from what I recall of the quick (and early in the data collection)
recap of the finds so far, most crashes were on the weekend so that
doesn't help.

Exposure is always the problem with things like this. You can match
crash numbers against licences and registration data but you can't
tell how many of those licenced riders actually ride and when and
where, you can't tell how many of those bikes are ridden by the
registered owner or where.

Doing any kind of counting is an expensive business, and in a city the
size of Sydney a very expensive one.

We see stats all the time in the papers. What we dont' see is what
they are based on, and how they've been derived. Start delving into
data sets that aren't based on personal (and therefore inevitably
flawed, read the literature on eye witnessses) observation, you
realise how dodgy it all is.

I do this when I see a car waiting in that position, and I call it
"Zeebee's wobble."
