Some stupid fast bus driver hit this poor taxi and turned it upside down. Look at tough body of this car, still intact, almost all of it, just a dent at front where bus, presumably, hit it.
Imagine if this was a Mehran or FX... you would only see a crushed peace of tin. Mostly mehran or fx taxi would have been sandwiched by the impact and whatever left would have been further crushed under its own weighed while turned upside down.
