So my brother has an aluminum bumper on his tacoma. Lady at his apt basically rolled her her car forward against it while looking at her phone or something and basically peeled her brand new Ford sedan open from the bumper to the door. Several panels just torn back. The pics were crazy. Shearing impacts are bad because they damage the frame horns up front. His bumper had some scuffs but was fine. Her insurance had the tacoma inspected for frame damage and paid him for the bumper.

Its basically how my last 4runner got totaled. Side impact took off front bumper and frame horns nothing else wrong but frame was a total loss.

If it was a garbage truck, those things have a ton of gps data and cameras. They film every single side of those things. Garbage truck hit my coworkers car last week. He got out looked at it while we stood in front of him then took off. Did not end well for him.
