Carmakers to tech partners: Keep your hands off our data

MACRO VS MICRO VIEW: While carmakers and tech companies wage war over user data access and ownership, the more relevant question is how comfortable consumers will be with sharing their personal information from the vehicle and whether state and federal regulators will want to impose limits on data-gathering and sharing.

SAN FRANCISCO/DETROIT: Carmakers are limiting the data they share with technology partners Apple Inc and Google Inc through new systems that link smartphones to vehicle infotainment systems, defending access to information about what drivers do in their cars.  

Auto companies hope that the vehicle data will one day generate billions of dollars in e-commerce, though they are just beginning to form strategies for monetising the information.
