I have two fronts and two backs. When around vehicles the flashing ones are pointed slightly so they don't annoy yet can be noticed. Also when around vehicles I switch which ones are flashing as one set is HIGHLY annoying. I am mostly on bike trails so when I do that both fronts are on steady and I use the annoying rear flasher but it's pointed down slightly. It is so annoying that people cannot ride behind me in a group. When in a group I use the lesser flashy one and turn the annoying one off.
