Terry Collins said:All you have to do is think about what Travis and co have posted and
look at it from a bicycling viewpoint. It really is very simple.
Hey Terry, you really need to come out from under the bridge.
Speed differentials are dangerous *when unexpected*. Drivers get used to
cars doing roughly the speed limit - behaviour other than that is
unexpected, and therefore dangerous. Cyclists normally travel at between
10 and 30km/h. Who here hasn't had a car pull out at 30 or more because
they didn't think you were moving that fast?
Danger on the road is a multi-faceted thing. I can do something stupid
every day for a year and not have a problem. Then someone else does
something vaguely stupid as well and we're both dead.
People in general aren't fast enough to accurately gauge the speed of
other vehicles. They assume speeds of of traffic +-5, which normally
works. Then someone is faster and appears from behind as they change
lanes, or slower and they run up the back. Good drivers constantly recheck
what other cars are doing against their model, and leave room to recover
from bad estimates. But most people develop sloppy habits because 99.9999%
of the time the first estimate is OK. A mistake normally means a minor
bingle - property damage, maybe some bruising, but everyone walks away.
But if these same drivers then make bad judgements when they do get into
trouble, big prangs happen and people get really hurt.
People driving too slowly are part of the problem here. They won't always
cause problems, but often enough that they're likely to be near one of the
drivers who is slow to recognise they're slow, or that they've caused a
blockage resulting in other traffic being slow. It's the combination
that's dangerous. Particularly when the escape plan for some people is to
swerve left, straight over the cyclist. I've seen that about to happen too
many times and been with it to get out of the way.
Slow bikes can cause problems like this, but we're generally easy to get
around safely, and drivers are used to seeing bikes doing certain speeds.
The flow on effects are fairly minimal. Someone pootling along a 1 lane
road can hold up cars for a very long time, resulting in big flow on
effects.
