Oh, there's still a chance you'll "interact" with a car, given the number of drivers who believe watching the road is low on their multitasking list at the time.
Bright, flashing lights will help. They can be especially helpful when the police show up, and the driver that just hit you says "I didn't see him", and the officer looks at your bike on the ground with the lights still flashing, shakes his head, and says "Uh-huh."
Don't ask me how I know.
