Me wonders if the optimizer ignores all the hints after the first misspelled/malformed one. What happens if you change the order of the hints:

FROM (SELECT /*+ INDEX(C PF_EVENTS_N2) INDEX(G PF_ACCOUNTS_U2) ORDERED driving_site(a) */

and

FROM (SELECT /*+ INDEX(C PF_EVENTS_N2) INDEX(G PF_ACCOUNTS_U2) ORDERED diving_site(a) */
