It isn't easy work, being a full time professional spy photographer. Even though you work with your camera on public roads, sometimes you'll have to endure abuse from the drivers of prototype vehicles. Skip to the 39 second mark of the video above to see a little spat between the driver of this next generation BMW 7-Series prototype and a spy photographer.

I think the spy photographer has grounds to report the test driver for abuse or threatening behaviour. If you don't want to be seen, then don't test the car on public roads. It's good that we've never heard of any Proton or Perodua test driver acting this way to all that rakyat that have been curiously snapping pix of their next generation hatchback prototypes.
