My other pet peeve is in-band communication without escape codes. Oh, the radio connected you so now you're talking to the other end. Oh, the link got dropped so now you're talking to the radio itself. What could have been a simple search-for-sequence filter now becomes a best-guess filter. Gaaaah makes my blood boil even 5 years later.
Honestly after my experience in firmware and manufacturing I'm amazed anything every works
I graduated EE with ('understanding' but) bafflement that radio works. Like just plain old amplitude or frequency modulated radio. Madness.
I work with software now/currently. I'd be surprised it all works if only it wasn't so frequently clear that it doesn't! I suppose the idea of updates has been quite quickly ingrained in the consumer mind - software bugs are somehow more acceptable, seen as just 'to be fixed' rather than 'broken' or 'poorly made', 'not very robust'.
