The PWS issue is not so simple.

“Predictive wind sheer tells if you continue on the present track 3 miles straight ahead you could kill yourself. Now it's your choice.”

True, but PWS is only looking at 40 degrees left and right of aircraft heading, less than half the sky. A turn away from a windshear icon on the nose could turn you into a worse windshear event presently unseen by the system.

I have managed to find a reference on the Honeywell web page that advises:

“Doppler processing limits the windshear detection region to approximately +/-40 degrees ahead of the aircraft. It is not uncommon to have multiple microbursts in the same area, so a turn to avoid one microburst might place the aircraft in a banked turn and in position to encounter another possibly more severe microburst.”
erm, does that Honeywell statement refer to Predictive windshear detection, or Actual Windshear encounter.
