I believe the consitutionality of traffic stops has been upheld because I would imagine in balance the benefit outweighs the cost. There is no probable cause there. Where is the line drawn at having to provide evidence (documents)of who you are, in some cases??

That's true.

Where is the line drawn at having to provide evidence (documents)of who you are . . .

A grandmother minding her own business on a city bus seems like a pretty good one.

The line is when you enter Federal land, they can set up a perimeter and check ID before letting anyone enter. No different from a military base. She was trying to enter onto Federal land and if she did not want to show ID she should have taking one of the bus routs that do no enter a Federal Facility.
