My speed obsessed son

A: Why are you speeding, Mommy?
Me: I’m not speeding. I’m going the speed limit.

A: It feels like your speeding.
Me: Well I’m not.
a few minutes later
A: Can you please go faster?
Me: No, I’m sorry, I can’t go faster than the car in front of me.
A: Why not?
Me: Because then I would hit him and that would be bad.
a few minutes later
A: I’m really tired of you driving so slow.
Me: Please don’t complain. I’m going as fast as I’m allowed.
A: Well, I really wish you would go faster.
