This makes a macro that returns a string of true/falses. I.E. 'True,False,True,False,False'. Then it splits the string on the comma to get a list of strings. I.E. ['True','False','True','False','False']. After that, it rejects any string in the list that is equal to false. So we end up with a shorter list of just trues. I.E. ['True','True']. Lastly, we count the number of items in the list, which will be the number of times that this statement returned true (car.box[3] - car.box[1]) > 0.4
