"Standard pilot training for weather avoidance". How do you account for the variations in radar equipment and what they show. Experience is a huge factor as well. Reading a radar display has a lot of subleties.
Maybe lets start with some standardized atc around the world. If the SID is runway heading, and you require a 90 degree turn off of that through an area of weather, maybe a heads up through the tower to your departures. We're not mind readers, and when you point us at an area of weather with no advance warning, then a cautious man should hesitate. Maybe the previous 5 went through and regretted it. I know I've done that in the past. Lived to tell the tale.
Yelling won't fix your mistakes, and creates an unsafe scenario.
