The crosstown rivalry between the Raiders and the 49ers has existed for decades.
And Oakland quarterback Derek Carr on Saturday provided a reminder of that.
Traveling in his car in California, the third-year passer came across a street named 'Forty Niner Way,' and immediately took to Instagram.

Carr posted a video of himself shaking his head at the street sign, with a caption that read: 'Raider Nation all day! #offseasonfun Clearly in the wrong neighborhood!'
Carr is coming off a 7-9 season, in which he threw for 3,987 yards and 32 touchdowns, and was named to his first Pro Bowl.Â
He played the 49ers once in his career - as a rookie in 2014 - and tossed three touchdowns and finished with a 140.2 QB rating in a win.Â
