Of course, if every bike had the required complement of lights, not many people would want to steal them for their own bikes... because, of course, their bike has lights, too.

I'm sceptical about this. As rider and driver, I've seen large nos. of cyclists with blinkies and,
AFAIK, have never been unable to judge how far away they are. I've certainly never found one suddenly in front of me whom I had thought further away.
Anyone any references to such research?
Not offhand, but it's out there, and I think it's been cited (or at least linked to) on BF in the past.
Motorcyclists have the same concerns, and go the extra step of adding lights to add width, making their speed & distance even easier to determine.
Honda's got a research prototype motorcycle with twin diagonal-shaped headlight assemblies, LED bars on the fork legs, and yet another light on a mast above the rider.
