While I can get behind most of the advice here, I don’t actually like the conditions array. The reason being that each condition function now needs additional conditions to make sure it doesn’t overlap with the other condition functions. This was much more elegantly handled by the
elseclauses, since adding another condition to the array has now become a puzzle to verify the conditions remain non-overlapping.To each their own. Some won't like the repeating code and some won't like the distributed logic (i.e. you have to read every if and if-else statement to know when the else takes effect). I think the use of booleans like
isDriverClosemakes the repeated logic less messy and reduces inefficiency (if the compiler didn't optimize for you).
