Been a weekend rider for awhile now and i'm starting to commute more and more. I've always read through these forums, magazine articles etc on how to continually improve roadcraft. And i've been applying these successfully. Even though i've been riding more and in times of heavier traffic i've had less and less close calls as time goes by(touch wood). This isn't due to better drivers around me but more my anticipation and early action to avoid the potential close call. Now when i ride i watch what's in front and what's on the side but rarely watch my rear. Would like to know does anyone continually scan their rear? Or is this an unnecessary action because the chances of being hit from behind is so rare? This does not include stopping at lights or occasional glances to check for tailgaters. Anyone ever been hit from rear whilst on the move?
