Do not do this. Not only will it unbalance you (a bad thing in the wet) it is entirely useless at determining the nature of the road, for obvious reasons. If you do it on a motorbike then you deserve everything that will happen to you.
Eh? All it involves is me moving a foot from the peg six inches or so down to the. surface for all of half a second - doing so involves little or no transference of weight to one side. I'm not the tallest guy in the world, but either feet can touch the floor while the bike is perfectly upright.
What are these obvious reasons why it's useless at determining the nature of the road? I'd expect having a physical feel for what traction the road offers provides a more accurate reflection than how it looks.
I'm here to learn though, so if you can explain why it's more dangerous than not then I'm all ears and will change my riding habits accordingly.
