No question this person is an idiot and should pay for the restoration of the street and the cost of the rescue. I'll bet his auto insurance will go up also. This sort of thing happens more than you might realize. In the resent past in a "Upscale" area in Johnson County Kansas a new off ramp from a major highway was put down in the mid-day. During rush hour several cars went around the barricades and drove up the off ramp. Some made it out, but after an untold number made it thru a couple of SUVs got stuck. Yes it was a mess. The drivers were charged, and the road contractor or county was able to get some of the expenses back from the drivers and their insurance companies. Too quote the comedian Ron White, "You can't fix stupid".
