Uber's success was built on developing technology that doesn't require the use of meters. That's like saying Apple should invest in pay phones.
There is only one example of Uber complying with regulations by installing a small number of meters in cars in an Indian province. That had nothing to do with World Moto and nothing to do with motorcycle taxis.
Uber is dealing with dozens of lawsuits over its business model. Their strategy is to argue they are not a taxi service therefore they do not need to comply with regulations. There is no need to speculate you can easily research this. Uber's strategy is to fight the lawsuits. It is not showing any interest in complying with regulations.
