Is it standard to try to land on a highway? A field would be a rougher surface. However, you wouldn’t be risking the lives of the people in the cars, and less chance of crashing into a cement barrier or whatever.
There will probably be youtube videos on this by pilotdebrief, etc.
Low enough and choices are very limited.
Based on a news report of the section of the Interstate that was closed following the crash, it looks like there are a lot of subdivisions in the area. Looks like they were trying for Naples airport rather than Southwest Florida. There were some golf courses to the west, but none of them look like they have a viable option.
