The International Space Station is a common sense test.
(17,500 MPH is about 10x the speed of a speeding sniper bullet btw) https://blossom.primal.net/9da462659b993041615a46da3d780217472028dcf76875f8...
You're ignoring elementary physics. It isn't speed that causes your head to tilt back and the silver to slip off the tray, but acceleration or deceleration. Once you reach a steady cruising speed, whether in a spacecraft or in a Fleetwood Cadillac, everything is as calm as tea time in your drawing room.
