This car is a Yankees fan and it doesn't care who knows it
Florida may only have two Major League franchises, but thanks to the Grapefruit League, its citizens have fifteen total teams to root for. Surely, this can create splits in team even among certain households -- like what we imagine is going on here between this driver and their car:
This car loves the Yankees. This car loves the Yankees so much it has made pinstripes a permanent part of its identity and has even (wisely) left a row on its bumper for future retired numbers.
And the driver? Maybe they like the Rays -- we really have no way of knowing at all.
