Immediately raised a red flag, since I've never heard of "steam gauges" until today, it took me a minute to realize they had confused the term, and obviously have no idea what they are talking about.

> Analog gauges, commonly called “steam gauges” because their faces resemble a steam pressure gauge

Contrast with "glass panels" or "glass cockpit" which just means "using a LCD" or similar (nevermind that the "steam gauges" also have a glass front)
