Everyone seems to have an attachment to rear blinkies. As an attractant device they make sense, but from a driver's perspective they are confusing in the extreme because they don't offer sufficient spatial positioning information.
If ppl were serious about safety then they would be promoting the use of a SOLID rear light accompanied by a blinkie attractor AND a reflector if required by law. The solid rear light provides continuous spatial positioning information for drivers approaching from the rear, as does the reflector.
So what's the deal with using blinkies on their own? Is the price of a couple of batteries worth more than the price of your life?
