Design a scene featuring a row of sleek sports cars lined up along a waterfront promenade during sunset. Modify the design by changing the car colors to vibrant blues and reds, and alter the tail light shape to a more angular, geometric style. Remove any logos or brand identifiers from the cars. Ensure the sunset casts warm reflections on the cars and the pavement, enhancing the overall vibrant atmosphere. Include palm trees in the background for a tropical feel.
