BRASILIA: Brazil's Senate approved a weaker version of a hotly disputed bill to regulate car-hailing services like Uber Technologies Inc on Oct 31 after the US company's chief executive warned it could make its business unworkable in the country. 

Dara Khosrowshahi, who held talks with senior Brazilian officials in the capital Brasilia, had called on senators to remove rules in proposed legislation that would require Uber drivers to be licensed with their local municipalities, like taxis, and to use their own cars.
