Answer 1

1. Set yourself a proxy of some kind of Charles, monitor requests.
By and large, there are only 2 options: either an open socket to which data is sent, or simply requests from the driver's application to the server. The socket imho is more correct.
2. In addition, forecasting / post-processing is used taking into account the road graph. This allows you to build beautiful lines in tunnels where gps does not catch by definition.

Answer 2

most likely push requests to the current location of the device.
