Tesla's 'Best Part Is No Part' Doors Spark Global Safety Probe

Regulators on three continents are examining the safety of Tesla's electric car doors, with concerns that designs could fail, trapping occupants or blocking rescuers. This issue stems from decisions made around 2016 during the Model 3's development, where Elon Musk pushed for virtually all controls, including doors, to be electric. This minimalist philosophy, summarized as "the best part is no part," aimed to reduce components and costs. However, these electric systems, powered by a low-voltage battery, can fail, especially after collisions, inhibiting emergency access.
