Oh yeah! Mario time!
March 10 is apparently Mario Day thanks to a clever play on words (aka MAR10), and in celebration of everyone's favorite Italian plumber (sorry, Luigi), Google has a fun Easter egg to check out.
The next time you open Google Maps, you should see an iconic Mario block next to the Start button for beginning turn-by-turn directions. After tapping on this, you'll get a pop-up asking you if you want to have your indicator turn into Mario driving his red-painted kart.
It's unclear how long this little treat will be available for, and while I'm not seeing it on my Pixel 2 quite yet, it should roll out to everyone over the coming day.
Safe driving and happy (almost) Mario Day!
