When walking in LA nowadays, use your Roman tourist experience of yesteryear.

"The Uber effect".  Got back to LA from Laughlin, NV.  When in Rome, there's #UBER.  Now drivers jet through intersections BEFORE the light turns green to "beat" the cross traffic.  It was an old Jeep Cherokee so it couldn't have been an uber car, but uber may have "drove" him to it.  Pun intended.  Hey, I coulda been a millionaire if only the State Bars hadn't canned me. Or I coulda been dead.
