Wanting new toys is not an exclusively human trait. Cats like playing with toys too. Rats have been taught to drive tiny cars. Orangutans have learned to drive golf carts. So why are your emotions more real then? Because a Mercedes can go faster than a golf cart?

Animals might not have the emotions for the same reasons, but they do exhibit the whole range we do. Anyone who's ever had an animal that can come and go roughly as they please, will know that they struggle with indecisiveness in all the same ways. Let me out, oh wait, actually never mind, let me in. Or out. Or let me in a little, I will keep one half of me outside and the other half inside, blocking the door.

Of course your car cares about your car related decisions...

The emotion part of your comment is just the love and the discomfort in the struggle, not the struggle itself nor any of the particular details.
