You could access some data directly via the OBD port with any number of devices/apps. This is an old standard though and moves are underway to create new standards including cloud data platforms.

As an aside, I doubt that cars are forwarding anywhere near 25GB/hr onto the Internet in normal (ie. non-test) driving. The cost would be horrendous and mobile networks would die in peak hour (for now).
