This is called sensationalization of the stats.
Taxis are a different category of vehicles from the other
vehicles.
Taxis are by default are destined to be kept on the move all
the times. It is not a park at Point A and move and park at
Point B vehicle. Which is what all the other vehicles are.
Being constantly on the move, it is exposed to greater
probability of collision with other vehicles or other objects,
including humans.
So the stats should not be surprising or shocking.
