The auto giants are in their typical auto giant mentality. "Ha, ha, haa, this chump has plunked down 25, 35 or 45 K to buy our car right? Now we can squeeze him dry. Want a nicely integrated map/system with the car audio and built in screen? That is special-nav package 3200$ for you. And we will stick you up for 200$ a year for map upgrades".
Google on the other hand gives me traffic update that is so granular and so up to date it boggles ones mind how they do it. Google paints the highways yellow, green or red, each section between exits gets independent updates. Last week, there was an accident in a non freeway some three lights ahead of us. The google map clearly showed the backup exactly up to the point, told us there is an accident ahead. It seems to be using some real time data about the number of cell phones passing in and out cell towers to determine the backup. Against this, goes our European wonders who bought Chrysler for 36 billion dollars and then sold it to Fiat for 6 billion dollars!
Google/Android is working towards an integrated auto-infotainment system standard. Apple is muscling in. Once the standards are published by SAE it is curtains for the auto industry selling GPS system at 2000% markup.
