Requiring the key fob to be activated in some way would prevent a good number of these attacks. For instance, a capacitive sensor could be installed on the fob that would only begin transmission when picked up by someone's hand and cease wireless transmission after some timeframe, say 2 minutes. This would at least stop many of the burglaries that occur at night when people are at home.
The auto manufacturers (and for that matter all the "IoT" creators) couldn't give two shits about protecting consumers. Building security into this stuff is trivial and a responsibility.
Civilians are now subject to an unprecedented level of surveillance. It would be a mistake to underestimate the probabilities of abuse of personal and private information. The 'justifications' for spying are as endless as the means for carrying it out; in 2001 it was Al Queda, today it's ISIL and tomorrow it will be something else. Exactly how these surveillance programs are implemented is beside the point. The results are very clearly a loss of privacy and freedom of expression. Whether or not you're likely to become a security threat will be left to the interpretation of bureaucrats rummaging through your Evernote entries and text messages.
