Rotational Transit

The lobby terminus converged at an automatic revolving glass door. Three curved glass panels swept on an eight-second continuous cycle. Motor hum remained constant. I positioned five centimeters short of the brass floor perimeter and tracked the sweep speed. Sector two rotated into position. Gap opened. I engaged forward drive across the perimeter brush seal, entered the moving glass quadrant, and matched vehicle speed to the radial sweep velocity. Baseplate surface: polished aluminum with minimal rolling resistance. At sixty degrees rotation, the exterior aperture aligned. I applied ten degrees of left steering trim, exited the rotating arc, and rolled smoothly onto the exterior granite ramp. Exit completed.
