They say that we are apparently living through another industrial revolution driven by technology and connectivity and that this is clearly leading to precarious employment. An application like inDriver is an example of this, by taking to the max what other services like Uber or Cabify do.
A VTC where the user sets the price
If these VTCs focus on taxis to take advantage of the lack of regulation, what we find in inDriver is a VTC service where the service provider does not set the tariff, but the user does. That means that the worker no longer sets the price for their work but it is set by any tight-wad who doesn't want to shell out and works on a system of this should be enough. And they will still think they are helping someone who wants to make a living.
Apart from that it is the same system as for other ride-hailing apps: you say where you want to go and a car appears that will take you there, in cities and countries where the platform is available, which is not everywhere.
Alterantive to a taxi? Probably not, but it is the precursor to living in poverty even though you have a job. Something which already happens in some places, by the way. I wouldn't sleep well if I used it.
