JAM-PACKED JOYRIDE BACKGRID
Patrick and Brittany Mahomes left an event in Miami Friday night in a golf cart ... and at least a couple people were hanging off the sides of it -- a move eerily similar to what John Elway's friend was apparently doing before he fell.
Photogs captured the two stars leaving club Carbone Beach in Miami ahead of the F1 Grand Prix in the area ... sitting in the back of a street legal golf cart.
They're not the only people on it, either .
