Goat Simulator and Surgeon Simulator are not simulators; they should be in a different genre as far as I'm concerned due to how little research went into them. If you want a simulator that actually, you know, simulates, rather than being just a silly Unity physics toy, I have some recommendations:
If you want a simulator that has distance abridgements for the sake of preventing boredom, I recommend Euro Truck Simulator 2 (and/or waiting for American Truck Simulator) off the top of my head.
If you want games that make minimal amounts of such cuts, I recommend Train Simulator 2014 (from a series formerly known as Railworks) or its rival, Trainz. Outside of trains, you also have the Ship Simulator series, with the latest one being subtitled "Extremes" (though the absense of Titanic compared to previous installments have turned some players off from it, in which case I suggest playing the previous version, 2008).
In the 2D beam-and-node physics simulation department, I suggest Bridge It (Plus, if you find you really like the demo) for bridges or Sinking Simulator, an indie game where you can make an image with colors representing materials, dividing it into compartments as you like, and then watch it sink, even break apart. Keep in mind, though, that Sinking Simulator is in alpha and the programmer seemingly deserted the project. For buildings and road vehicles, go for "Phun".
For 3D beam-and-node simulations, Rigs of Rods and its better-graphics-but-younger-and-less-popular sibling BeamNG.drive should be your one-stop shops for vehicle crash simulators.
All of the above except for Rigs of Rods, BeamNG.drive, Ship Simulator 2008, Sinking Simulator, and Phun are available on Steam. If you need help finding the non-Steam games, let me know and I'll happily show you the way to their websites!
Welcome to the world of the simulator genre!
