The last 3 are actual crimes. Sure they aren't DUIs, but I wouldn't list them as valid reasons to avoid checkpoints.

"I want to avoid interacting with the cops because I committed other crimes they might punish me for" is not a good argument.

The question was "What purpose outside abetting in avoiding a DUI is there for publishing a live map of DUI checkpoints?".

As a technical point, being an undocumented immigrant is still not a crime in the USA though it can result in law enforcement actions with impact as severe as criminal penalties. Expired registration or insurance is a civil infraction rather than a crime in some jurisdictions.

Edit: I should clarify why it matters that some of these are civil infractions rather than crimes. Navigation apps that Apple allows, including Apple's own maps app informs users about police and speed cameras, which helps people violate the speed limit without being punished. There doesn't seem to be a coherent principle at work here though.
