Continuity mistake: When Ryan Gosling first goes to meet Eva Mendez in the diner, she comes from the back and delivers a fair amount of food on three or four plates to the table just behind Ryan's left shoulder. When the camera angle changes to in front of them the table is now visible and has no food or plates on it, with the diners sitting waiting patiently for their food. (00:09:48)
Continuity mistake: Luke's motorcycle can't decide if it's a 2-stroke (in the circle cage), or a 4-stroke engine. It seems to be the high pitched wail of a 2-stroker when there's a chase, but has the mellow burble of a thumper when he starts it for his son. This changes back and forth at least 4 times.
