Probably because Drive isn't nearly as well-known as the other two (and the possibly faux-one); it's a cult classic but little more. Although I've never seen or heard of Mimic 2, or even a Mimic 1 for that matter, I'm sure more people have seen it and the pretty popular Disney schlock thing Wendy Wu than they have Drive. It's the same reason Yuen Wo Ping's projects always have him listed as (Crouching Tiger Hidden Dragon, The Matrix, Kill Bill) instead of his better work.
