How gliders, hang-gliders and that ilk don't have more mid-airs is beyond me.
On hangliders, we're used to flying in a gaggle of up 100 others in competition and so we always check behind before initiating a turn. In our club, we do get some mid-airs between paragliders but they seem used to flying close enough to chat in the air.
