Tesla Pivots to In-House Mapping to Solve Persistent Full Self-Driving Flaws

Tesla is developing custom maps to resolve persistent Full Self-Driving issues like incorrect speed limit recognition, parking navigation, and route selection. The move represents a major strategic shift after years of leadership criticizing map-dependent autonomous systems as fragile. By leveraging fleet data to build proprietary road models, the automaker is adopting a mapping strategy increasingly similar to rival robotaxi developers.
