Depending the precedencees instead of using parantheses is just one more way to make C unreadable.

... religiously following that one MISRA-C rule about not placing any dependence on C operator precedence is one of the fastest ways of turning legible code into a perfect mess.

(Hint: Lots of things in C are operators - array accesses "[]", member accesses ".", member accesses from pointers "->", address-of "&", pointer dereference "*", unary plus and minus, assignments, and so on, are all operators that do have a place in the precedence table.)
