  Modern cars technologies are evolving quickly. They collect a variety of
personal data and treat it on behalf of the car manufacturer to improve the
drivers' experience. The precise terms of such a treatment are stated within
the privacy policies accepted by the user when buying a car or through the
infotainment system when it is first started. This paper uses a double lens to
assess people's privacy while they drive a car. The first approach is objective
and studies the readability of privacy policies that comes with cars. We
analyse the privacy policies of twelve car brands and apply well-known
readability indices to evaluate the extent to which privacy policies are
comprehensible by all drivers. The second approach targets drivers' opinions to
extrapolate their privacy concerns and trust perceptions. We design a
questionnaire to collect the opinions of 88 participants and draw essential
statistics about them. Our combined findings indicate that privacy is
insufficiently understood at present as an issue deriving from driving a car,
hence future technologies should be tailored to make people more aware of the
issue and to enable them to express their preferences.
