A typical feature of technologies using autonomous forms of control is their increasing complexity resulting from the increasing degree of automation, which, in relation to the process of their use in everyday life, will present new risks that mainly increase when autonomous systems are used in urban public transport, where there is a higher risk of causing harm to the health and life of a large number of people at once. These risks are linked to the issue of the functioning of a civil liability regime that would reflect the distribution of risks in relation to the direct user, manufacturer or operator of the autonomous system through the expected standard of care. The paper shows in which direction and on what basis considerations could be taken when defining the expected level of care and to what extent the current setting of liability relationships is also applicable. Finally, we will present pilot legislative changes in some countries regarding liability for autonomous vehicles and outline the new Product Liability Directive regime for software developers.
