Los Angeles police saved countless lives by impounding starlet Amanda Bynes' car this weekend when she was (again) pulled over and finally punished for driving with a suspended license.

Bynes has long been thought to be in the throes of some sort of substance abuse problem, but recent stories have emerged that even cast doubt on the state of her mental health.

Bynes' black BMW was pulled over in Burbank, Calif. at 9 a.m. on Sunday, and when cops figured out who was driving, they ended her long reign of terror by locking up her car.

A lengthy string of collisions in a very short period of time and recent photos of the actress smoking pot in her filthy car last week have made even us wonder what the hell is going on with Bynes, and we're not the only ones. Several people in close proximity to Bynes, including those who frequent her West Hollywood gym, claim she's been exhibiting signs of certifiable cray-cray.

One gym-goer claims to have seen Bynes dazed and talking to herself last week -- and yeah, we all talk to ourselves sometimes, but Amanda was apparently making statements and then answering them herself like a one-woman debate team. And someone else revealed that while on the elliptical, Bynes laughed hysterically for no identifiable reason, taking the "runner's high" to a whole new level.

What's more, her neighbors have seen her having long chats with inanimate objects.

Time for an intervention, we thinks. But if that happens, we're guessing her managers and publicists will film it and milk this misery for all its worth.
