Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
How would you approach debugging a localization drift issue in a dense urban environment at May Mobility?
Explain how you would distinguish sensor, map, perception, estimator, and vehicle-motion causes. Describe the data you would collect, the experiments you would run, how you would protect passengers and other road users during investigation, and how you would validate and deploy a fix.
