This is the code I have so far on p$5.$js:

function setup$()\{$

createCanvas$(500,200)$;

background$(220)$;

fill$(255,0,0)$;

car$(50,50,50)$;

fill$(0,255,0)$;

car$(90,150,30)$;

car$(250,50,100)$;

$\}$

function car$($x$,$ y$,$ h$)\{$

push$()$

rect$($x$,$y$,2*$h$,$h$)$

fill$(0)$

circle$((2*$h$)*0\mathrm{.}25,$x$*2,$h$/2)$

circle$((2*$h$)*0\mathrm{.}75,$ x$*2,$h$/2)$

pop$()$

$\}$

I've been messing around for so super long trying to get the 'wheels' right but everything I do will always work for $2$ of the rectangles but not the third. What is the code for both circles??
