Mechanical Dinosaur in the city

Sunday morning overtime for the the dinosaur driver!!

Very scary how precise the driver was. The machine looks like a prehistoric dinosaur and moves with extreme precision. Every bite of it's 'jaws' sears through concrete and steel re-inforcement with ease, all at 10 storeys height.
How they know that they're not going to topple the building onto the street behind me is beyond me, it was still open to cars and the walking public, wouldn't want to explain that to my insurance!!!
