Query: Personal space of autonomous car's passengers sitting in the driver's
  seat   This article deals with the specific context of an autonomous car navigating
in an urban center within a shared space between pedestrians and cars. The
driver delegates the control to the autonomous system while remaining seated in
the driver's seat. The proposed study aims at giving a first insight into the
definition of human perception of space applied to vehicles by testing the
existence of a personal space around the car.It aims at measuring proxemic
information about the driver's comfort zone in such conditions.Proxemics, or
human perception of space, has been largely explored when applied to humans or
to robots, leading to the concept of personal space, but poorly when applied to
vehicles. In this article, we highlight the existence and the characteristics
of a zone of comfort around the car which is not correlated to the risk of a
collision between the car and other road users. Our experiment includes 19
volunteers using a virtual reality headset to look at 30 scenarios filmed in
360{\textdegree} from the point of view of a passenger sitting in the driver's
seat of an autonomous car.They were asked to say "stop" when they felt
discomfort visualizing the scenarios.As said, the scenarios voluntarily avoid
collision effect as we do not want to measure fear but discomfort.The scenarios
involve one or three pedestrians walking past the car at different distances
from the wings of the car, relative to the direction of motion of the car, on
both sides. The car is either static or moving straight forward at different
speeds.The results indicate the existence of a comfort zone around the car in
which intrusion causes discomfort.The size of the comfort zone is sensitive
neither to the side of the car where the pedestrian passes nor to the number of
pedestrians. In contrast, the feeling of discomfort is relative to the car's
motion (static or moving).Another outcome from this study is an illustration of
the usage of first person 360{\textdegree} video and a virtual reality headset
to evaluate feelings of a passenger within an autonomous car.
