Dear monday,
"If signing a ticket is so important, however do they prosecute traffic infringements that are caught on camera and where the tickets are sent in the mail?"
At least in jurisdictions in this region, camera-generated tickets only generate fines, not points on one's license. This is precisely because of identification problems.
That being said, the Polaroid solution sounds like the right one, here. The law should not be written in a way that takes a minor issue - failure to sign a ticket for a very minor offense - into a major issue.
