"Mommy, 'tar poming" (car coming)
Yes, dear, I see it. Thank you.
"Mommy, not go too fast"
"'tars go slow?"
Yes, the cars are going slow."
"Mommy, go slow"
Good idea. Even though I really wish I can get my car equipped Mario Kart style and shoot stuff at the idiot cars in front of me.
Or, my favorites:
"Mommy, not go too fast. 'tay? 'tay!"
"Mommy, not go too fast. Hear me? 'tay!"
