Inter-vehicle communication has to be able to copewith adverse conditions like received signal strength fluctuations,channel load saturation, or high mobility to provide robustcommunication services as a basis for safety-related applications.We show the impact of realistic radio models on the performanceof vehicular ad hoc networks. While most of the implications areknown, some of them appear to be underestimated in vehicularscenarios. We want to convince protocol designers of `thinking inprobabilities' when intending to achieve reliable communications.Among the contributions of this paper are a discussion oflink layer desynchronization, a derivation of probabilities ofbidirectional links and associated costs, and a fairness concept.
