Verse 
F#— she left us but now the roads open 
B— to new billboards, watch your windows pass the old ones by
D#m— she left us switching lanes without 
A— checking the rear view, take your chance we'd never die

Mumbling (same as verse )

Harmony
F#— come drive with me we are 
B— going to the south, you can 
D#m— sit passenger but bitch 
A— don't run your mouth 

The entire song switches chords every 8 beats.
i'm not 100% sure about the b and a chords but the f# and the d#m i am pretty sure 
that they are right
