World's Fastest Grandma Cinematic Comedy

A quiet suburban street at sunrise. An elderly grandmother slowly pushes a shopping cart toward a grocery store. Suddenly she notices a SALE sign in the distance. Her expression changes with absolute determination. She launches forward. The shopping cart breaks the sound barrier. Sidewalk cracks explode behind her. She races through cities, deserts, mountains, and oceans while maintaining perfect grandma posture. Fighter jets struggle to keep up. Scientists monitor her trajectory from mission control. The grocery store employees nervously prepare. Final shot: she arrives exactly as the doors open, calmly takes the last discounted loaf of bread, smiles politely, and walks away. Hyper-detailed cinematic comedy, extreme speed, escalating scale, realistic physics treated seriously, dynamic camera angles, no text, no logos.
