This is not a dig at instructors but a dig at the training syllabus which needs to put far more into handling and not playing with fancy displays
It does not matter what the syllabus is - a decent instructor should be making sure his student is competent. Having said that, I think there are many pilots that might be competent when they get their licence, but it might be a few years down the line that they buy a Cirrus and many pilots do not keep up to speed with the basics, so it may be nothing to do with the basic teaching!
