Most of the time, I don't even have enough time to look at the objects clearly so it just disappeared from my view.

It's definitely not a tire, because damaged car parts/tyres are often picked up from the road immediately to prevent road hazards.

It doesn't do anything at all, it's just there and normally it's quite unusual to see objects big enough to be seen on the road. Currently, I can't rule out any causes, but I have been sleeping a minimum of 5 hours to a maximum of 6 hours each night due to gaming.

I could write these down in my notepad for future pdoc reference. Thanks a lot, you've been a great help!
