I like the fact that this is in the news... and that they state that this "sting" operation will be going on for months, and that officers are undercover. That means any cyclist can be seen as an undercover cop in a sting operation, with backup cops. I think motorists in San Antonio are going to be giving cyclists more room.
Now on the flip side... I have to admit that I am incredulous that California and San Diego in particular are not "advanced" enough to have either such a law, nor enforcement, nor even the bike racks shown in the story.
We may have nice bike lanes nearly "everywhere," but these are often on 50MPH+ roads and drivers are still too damn close.
