I challenge the fundamental premise that SDCs will make them profitable. There is no stickiness to their business model. Moving on to another ride sharing service is frictionless today. Most people I know use both Lyft and Uber. So if tomorrow SDCs become popular and offer a cheaper rate, people will move to them in droves. Nothing stopping them. We know Uber and Lyft are way behind on SDCs compared to Google on that front. It also looks like GM and Ford could there before these two. So what makes them a good investment either in the short or long term?
