What else have I got?
Take it from me I use EGPWS (GPWS before that) and weather radar every day of my working life, in Class 'A' airspace. (EGPWS is of course based on a system accurate enough to post a cruise missile through a letterbox!) I held a procedural Master Green instrument rating when I flew Chinook.
Because at that time, the majority of Chinook flying was entirely overland at low level, for 90+% of the flying weather radar would have been useless! Even when IFR airliners can despatch without weather radar (and I have) it's just that weather restrictions become a little more limiting.
Perhaps your flying experience is less wide-ranging?
