  With progress in enabling autonomous cars to drive safely on the road, it is
time to start asking how they should be driving. A common answer is that they
should be adopting their users' driving style. This makes the assumption that
users want their autonomous cars to drive like they drive - aggressive drivers
want aggressive cars, defensive drivers want defensive cars. In this paper, we
put that assumption to the test. We find that users tend to prefer a
significantly more defensive driving style than their own. Interestingly, they
prefer the style they think is their own, even though their actual driving
style tends to be more aggressive. We also find that preferences do depend on
the specific driving scenario, opening the door for new ways of learning
driving style preference.
