hydraulic fan motors...wtf?

Probably saves them money,lol. I have seen a couple of newer brand X vehicles
in the dealership recently w/them. I find it disturbing that they think its OK for electricity
to control the throttle and steering instead of me,but it's not up to spinning a fan in the
same conditions.I'm sure in a truck/SUV app. where water,mud and such may get at the
fan assy. (if you're actually using them off-road in those conditions), the hyd. system may
prove more reliable.
Other than taking some load off of the ever increasingly loaded electrical systems,
you know,everybody has to have 5 DVD players and screens for every spoiled rugrat etc.
money and operating cond. are the only reasons i can think of.
Variable electric fans have been around for decades,and fan noise is pretty much
controlled by blade design,the motor itself is silent really.
