Design a phased migration plan for Autopilot without hurting users

Problem Statement Description

Product context: Tesla is an electric vehicle, energy, and software company; its products include EVs, charging, vehicle software, Autopilot/FSD features, energy storage, and solar products.

Tesla is preparing to migrate Autopilot users to a new version of the Autopilot experience across supported vehicles, with particular attention to road trippers who depend on highway driving assistance over long distances. These users often combine Autopilot with navigation, charging stops, variable road conditions, and fatigue management, so any disruption could directly affect trust, safety perception, and trip completion.

Your task is to design an execution plan for a phased migration that protects the current user experience while enabling Tesla to move users to the new system. The plan should account for software rollout realities, vehicle compatibility, safety monitoring, customer communication, support readiness, and the ability to pause or reverse the rollout if issues appear.

This is an execution-focused question. The emphasis is not on designing Autopilot itself, but on how you would operationalize the migration across users, vehicles, regions, and use cases without creating avoidable safety, usability, or customer trust problems.

The experience should consider:

- Which user segments, vehicle configurations, geographies, and trip types should be included in each migration phase

- Preconditions and dependencies, such as software readiness, map/data quality, hardware compatibility, service coverage, and support training

- Go/no-go criteria for expanding from internal testing to limited beta, broader rollout, and full migration

- How to monitor safety, disengagements, user complaints, navigation or charging-related friction, and trip disruption during rollout

- Communication to drivers before, during, and after migration, including what changes, what remains the same, and how to get help

- Rollback, pause, or fallback mechanisms if users experience degraded performance or unexpected behavior

- Cross-functional owners across Autopilot engineering, vehicle software, safety, data, customer support, legal/compliance, and field operations

The goal is to present a clear phased operating plan that balances speed, safety, user trust, and execution discipline. Your answer should make it easy to understand who does what, when the rollout advances, how Tesla detects problems early, and how users are protected throughout the migration.
