Misted mirrors

[Neil A]

More a question of curiosity...just remembered that in May I was riding the (2004 1200) GS through Wales and over the space of about an hour, the mirrors misted right up, then cleared, then misted - about half a dozen times. About 9-10 am, clear day, bright, pleasant but not really warm, plenty of changes in elevation but no shadows from trees or anything...just wondered. You'll notice I wasn't that curious (left it months before I remembered) and for the sake of the safety conscious (all of us, I hope), I should point out that I maintained rear observation by looking behind me. Long gone are the days when I thought if you were going fast enough, you could afford to concentrate primarily on the road ahead

Same here . 2004 gs. . . .they just do that when humidity is high and you ignore the speed limits . . . ?!!!?@ for us here almost all year round

 

[Neil A]

Speed limits?

Thanks. I do recall some low-lying mist at the start of the journey.

We certainly have humidity here on the Island, but we don't have (National) speed limits, so therefore I haven't been able to ignore them. It was only that I happened to be in the UK with the right combination of circumstances.

Is it built in by BMW to stop you seeing the flashing blue lights and slowing down before you can be pulled over and clapped in irons? Blimey - they certainly were keen to curry favour with the traffic cops and sell them motorbikes.

But....I certainly wouldn't have been ignoring the speed limits in Wales, by the way, Officer

WTF ?

Mine do that. But I can reach froward and wipe them with a gloved hand

Get some Bob Heath Visor spray on them.

If you had the ambient temperature computer display, you would have noticed the air temperature rising/falling by a degree or two as you went through dips in the landscape, coinciding with the mirrors misting over and clearing again. In still early morning conditions, cold air collects in valleys etc (later in the day, the sun will warm the ground, causing the air to circulate due to thermal currents, but not first thing in the morning).

Warm air is able to hold more moisture than cold, but as you move out of cold air into warmer air, the mirrors stay cold for a minute or two (until warmed by the air). At this point some moisture condenses out of the air, causing fogging of the mirror.

 

[Neil A]

Yes,,,,

WTF ?

It's a fair point - I'll get my coat

 

[morty]

take them off you don't need them but I'll have them its not foggy or misty up here

 

[Ogmios]

My bathroom mirror does that when i shave.


Never realised it went that fast.

Is this why the windows frosted over - so you dont notice the scenery rush by?
