I drove a lowered Miata for 7 years/200k miles. If there was a beer can laying on its side in the road, it would catch under the car. To this day, I still clench up when I see debris on the road. It will get tiring, I promise.
Scariest debris I ever encountered: a full size, heavyweight dining room table, standing upright in the middle of my lane on I-85 at 3:00am, when I was doing triple digits. It was so out of place, that my mind could not register what I was seeing. The table top was at about head level. I barely missed it. I could see the friggin wood grain on it as I passed. I can only guess someone lost it off the back of a pickup.
