General Motors' self-driving taxi service Cruise has ceased operations nationwide after California regulators revoked its license due to public safety concerns. GM has faced substantial losses, with Cruise accounting for $732 million of GM's third-quarter losses. But while the company has faced setbacks, the broader autonomous driving vehicle industry has been steadily advancing, Edge Case CEO Michael Wagner tell Yahoo Finance. He believes Cruise's suspension "is a symptom of poor safety culture at Cruise specifically" rather than the whole sector.
