Rainbow Dash does food deliveries in her mom's 86 around Ponyville and Mount Canterlot, little does she know that she beat Pipp Petals in a race on Mount Canterlot which raised tensions between the Ponyville Speed Bolts and the Zephyr Heights Velocity Queens, Rainbow is about to have a wide adventure coming across drift battles and some character development as she goes through the life of a street racer. (Author's Disclaimer note I'm aware it sounds like Initial D but major scenarios will be different like how cars react to the ponies' magic and how Rainbow Dash won some races with her speed magic and her iconic sonic rainboom which may result into getting her cutie mark to sparkle and glow and most of all where rainbow dash and made friends with Pinkie, Fluttershy, Spitfire, Soarin, Fleetfoot and Misty Fly so technically will be a slice of life for Dash)
