I do mount my rear light down by the drop out, so that it lights up the wheel, providing side visibility as well as rear visibility.
You're correct about the light being reflected straight back to the source with the older styles of safety shirts/vests.
Be on the lookout for the newest version of safety wear with 'retroreflective'. It lights up with light from any angle.
I work in highway construction and the new material is now mandatory, at least for us inspectors.
