Back seat driver

Lauren • 28. Married 1/17/14. Had our first baby 1/14/16! Second due July 2017
My husband despises when I warn him about something while he's driving. Like someone crossing the street and I feel uncomfortable with how fast he's driving so I say "someone's crossing" he just gets very annoyed and I guess offended that I'm "correcting" him like he can't drive. 
Today I saw a toddlers feet running (under the cars parked in driveway) down the driveway with her mom chasing after her, so I said "be carful there's a kid running towards the street. And he gave me all the attitude he could and was just sooo mad at me. I can't believe it! He could just say "yea I see thanks".  I think it's worth saying something IN CASE he didn't see it happening. Idk
