The concept of 4 main cars of life, was born in the process of drawing animation.

At first it was a concept of 3 cars:

    1) a car, taking you from the maternity hospital,

        2) a police car, taking you to the police station, and

3) an ambulance, taking you to the hospital.

Then, in a conversation at the bar, my friend added a fourth car - a hearse.

Unfortunately, the fourth car went outside the script

and did not appear in the final cut, but you can see it here.
