I have drove in 49 out of 50 states (never been to Hawaii) and Illinois ranks the worst in my opinion. It’s like they ran out of asphalt and stopped doing any repairs 10 or 20 years ago.
To people not living in the U.S., feel free to complain about your country’s roads too.
How is Alaska? It must be very difficult to have good roads there.
Depending on where you are there just aren’t any roads, or the roads don’t see heavy trucks so they stay decent.
