Then of course there was the dual The Phantom Menace and A New Hope callback to Beggar's Canyon when Din Drajrin mirrored part of Anakin's pod race run. In Episode IV, Luke compared the Death Star Trench run to that same Beggar's Canyon through which he and Biggs raced their T-16's.

Those callbacks are just scratching the surface (spinning is a good trick), but there was one aspect that was a straight up tribute to George Lucas as a person. He grew up immersed in the California car culture and is a self-described car fanatic.

Even when Mando revs the engines, it sounds more like a V8 than sub-light thrusters. This was a loving tribute to George Lucas, and it was great to see that coming from Disney.
