She also has an obsession with shadows. At a young age someone exposed her to a laser light and I think that's the reason she's hyperaware of shadows and lights. She constantly digs at the kitchen floor when she sees a beam of light, and she'll chase a reflection of light up the wall. A firm no has done nothing to change this. She's been doing this for a couple months.
This is OCD and cannot be addressed with an e-collar, and as martem said, none of your issues are "e-collar material".
Look up "stereotypy in a dog" or "OCD in a dog" and see what you can find.
Often dogs such as this need medication and behavior therapy to get over their ocd.
Take her away from the busy road or erect a solid fence for the danger there.
