tips

Have you ever been confronted with the need to drive in the fog? I can remember

many many days of riding between L.A. and San Francisco where I found myself

suddenly closed in by a fog bank. Those were scary times, for several reasons.

If you cannot see two seconds ahead of you, of course, you should get off your

bike. That's not an issue many would argue. What is, however, is the nature of

accidents that you can expect if you ride in reduced visibility environments.

Besides what we all understand as risks (that you will ride into something you didn't

see, or that somebody will ride into you, for the same reason), I suggest that the

most serious problem likely to happen is that you will drop your motorcycle - for

apparently no good reason.

It makes sense, actually. With limited visibility you are unable to see the horizon.

Passing trees give you some hint of vertical, but not always reliably. Anyway, if you

are in a curve and must stop quickly, you have no way of knowing if the bike is

vertical when you get stopped! Before you know it you find the bike falling over and

you are unable to stop it. All because you could not see the horizon, (even though

you do not consciously look at it in order to gauge vertical.)

Who'da thunk such a thing?

Another interesting phenomena that a reader pointed out to me recently is that studies have shown that people tend to
gradually increase speed while driving in the fog. I didn't know that and cannot recall that I have had that happen to me,
but I certainly understand how it could happen. With any experience at all we tend to look at our speedometers rarely as
we can judge pretty well what our speed is using the passing scenery for cues. In the fog those cues are unreliable.
