When I ride across cobblestones with 28's it is like hitting the brakes.

Where did you find a cobblestone road in the San Francisco east bay
region?  I've never seen such a road, much less ridden on one.

I found only one on Potrero Hill:

Wow.  That must have been a really amazing ride.  Did you go up, down
or slalom?

and a little history indicating that "pavers" were once used on South
Beach:

Cobblestones were not used very often in the US during the 20th
century:

So, where did you ride on cobblestones or would you perhaps prefer to
rephrase your claim?
