ANSWER:

This is not shirk but sinful as you are breaking the law of the land you’re living in and threatening the lives of others while bringing a bad name for muslims for being irresponsible. 

When I am driving and texting at the same time, and then I see a cop and put my phone down, is this shirk? (Since Allah was watching me I didn’t stop but for a cop I did…) this has been stressing me out a lot because sometimes I use my phone when I need to when driving.
