Sounds great but the advantage the main guys have is the network effect, a large fleet. The fact that this is free suggests no marketing budget and therefore less drivers and passengers, both which depend on each other to grow.
It's also a good starting point for local companies to be the Uber or Lyft of their city. For example in Toronto, Hailo doesn't exist and Lyft doesn't operate here either. It would be awesome if a company could just pick up LibreTaxi, pour in some $$$ for marketing and sales and start it up for Toronto.
