Uber is a transportation company headquartered in San Francisco that offers various cab services through its app. It has a valuation of approximately $70 billion and CEO Dara Khosrowshahi. Uber uses surge pricing technology to calculate fares and has expanded into other transportation services like boats, helicopters, and food delivery. It faces competition from Lyft and traditional taxis. Some issues Uber has faced include lawsuits over its self-driving technology, protests from taxi drivers, and a sexual harassment scandal that led to firing 20 employees. To address issues, Uber needs to follow local laws, provide benefits to drivers, and enhance background checks.
