4th amendment still applies to those engaging in the 'privilege' of driving to work so they can pay the property taxes they must pay so they aren't locked in jail for being homeless.

Idea 4A doesn't apply to 'privileges' including the most common method of personal transport is totally nonsensical nor is any exception of the sort implied nor explicitly outlined by the amendment.

Your right to privacy is subordinate to the public's interest in identifying the drivers of cars.

It's not a 4A violation to require you to display ID when you're driving a machine that statistically is one of the leading killers of both adults and children. It's just good policy.

Identifying ( by essentially always-on search) everyone driving without RAS or PC sounds like a privilege and not a right, that can be revoked, unlike the 4A.

As ALPR become ubiquitous it's becoming clear that privilege is subservient to our rights.
