>A lot of folk that ride recumbents (in so much as there are such people!) think that the WTF is that? factor means that they get a bit more attention than a normal rider wth every visiblity aid going. I could buy that.
As a recumbent rider, I *can* vouch for the fact that that's true, certainly in assorted traffic conditions in N Surrey/edge of London.
Flags ? - jury's out on whether they help, but I'd rather not carry one - I have to put up with ever more prats shouting out of car windows (Clios are the new Nova?) than on a normal bike, giving 'em something to grab hold off strikes me as a bad idea !
Ah, just reread the above - he's got a trike. Mine's fairly low but a 2 wheeler - seat's about 14 inches off the floor, so my head's at driver level (good for giving 'em the evil eye when they start doing a stupid overtake. Trikes are good fun - human powered karts - but I'd be wary of using one in busy traffic - which is why I settled on mine.
Must admit I'd be more inclined to try a flag on a trike.
That said, there was an old fellow used to live nearby - popped off at about 99 after 30ish years of cycling (ill health, not under a truck !) - and he had several trikes, tho' he probably was out on them outside peak commute times.
