However, people may not feel completely safe in and around autonomous cars since the control of the car is taken from the occupants. There have been accidents involving autonomous cars, even with casualties. The unconventional seating plans suggested for autonomous cars can put the occupants at more risk unless new restraint systems are designed. There will also be a transition phase of mixed traffic flow which will involve both autonomous cars and conventional cars; this can complicate the decision making process of autonomous cars. Safe transportation with autonomous cars also requires good road infrastructure. Personal data security and hacking are also other concerns that occupants have to deal with. In order to investigate the cultural attitude towards the safety of fully autonomous cars in Turkey, 21 males and 20 females aged between 11 and 60, were interviewed and 12 questions were asked. Only 30% of the participants said they would feel completely safe in an autonomous car. This study can be useful for researchers who study cultural differences in the attitudes of societies towards autonomous cars. What's more, the presented ideas for seating and restraint systems can be of help for designers.
