Can you imagine not paying attention and hitting this thing? I don't even think your tire would blow or your car would get stuck. I think you'd instantly be transported to another dimension. Like the Upside Down or at the bare minimum Fraggle Rock.
The best part is this won't even impress the average Chicagoan. This is a divot here. Just standard operating procedure for when the weather warms up here and the ground thaws. Giant gaping holes appear and the streets and sanitation guys come and fill them up with those styrofoam peanuts, slap a coat of black paint on top and call it a day. Sure you might be right back in that same place repatching the very same hole in 10 months but it’s all about ensuring you have a job.
