It's an established fact that Amanda Bynes would wipe out the orange cones in the simplest of driving tests these days. Even veteran Los Angeles police officers -- who've probably seen every heinous act known to mankind -- are worried that she'll kill someone.

Bynes was snapped toking up behind the wheel of her squalid, trash-strewn BMW earlier this week, which made us hope she's not actually living in that thing because she'd need a tetanus shot first. But between the alleged partaking of herb (not to mention who knows what else) and her long list of hit-and-run charges, cops are worried about the safety of her fellow motorists.

Anonymous officers spoke out, with one saying, "She's addicted to something and she's driving a deadly weapon and is going to kill someone. It scares the s--- out of me."

Another member of the LAPD said, "The public should be afraid of her. From looking at the photos, and what she's smoking, she has no sense of reality. If she's not stopped she's gonna kill someone." Meanwhile, a veteran on the motor squad rated her a 10 out of 10 on the danger scale.

Maybe it's time she stop saying "no no no" to rehab and just go already -- before she racks up any more casualties than her already-dead career.
