Now look what we did now, the cops behind us
Ran that red light, did you have to be mindless

from Malik Yusef (Ft. CyHi The Prynce, John Legend, Teyana Taylor & Travis Scott) – Sin City Lyrics on Rap Genius

Meaning

Speeding through a red light is not something you’d want to do in pretty much any situation, but when your in possession of some illegal drugs like Travis and girl probably are, unwanted confrontations with the cops is the last thing you want, and only someone without a brain would do something like that. Considering the context of this line, the girl who’s driving was high while driving through the light.

He’s SMH'ing in the next line because of the person who pointed out the running of the red light. “I KNOW! I KNOW!”
