Respectfully,
The ground was basically flat for a great distance in every direction. There was no need to make any decision to clear the road/trees. That was a very minor obstacle to a 737-800.
there was a six lane motorway across the flighpath and also some (industrial?) buildings along that road, about 10 sec prior to where the airplane came down.
I agree the trees should not have been a factor, but a packed highway may be different.
