How can you tell.....

Also, helmetless on the wrong side of the road just reeks of newbiedom...

Where I was from, that reeked of a poor public transportation system Especially because it was usually helmetless, wrong side of an eight lane highway wearing dark clothing.

It's sort of sad that many of those who bike because they have to (rather than want to) are the ones who know the least about what they're doing. And interestingly - at least where I used to live - were far more likely to get ignored rather than screamed at by passing motorists.
