1. A method for plausibility check in a vehicle-to-everything (V2X) dynamic environment in which a local vehicle communicates with remote vehicles, comprising: a) obtaining a measured Received Signal Strength Indicator (RSSI) from a specific remote vehicle; b) calculating an expected RSSI for the specific remote vehicle using a dynamic RSSI model; c) performing a respective plausibility check for each of the specific remote vehicle and the local vehicle using the specific remote vehicle measured RSSI and the calculated expected RSSI, and, based on results of the respective plausibility checks; d) deciding on respective further actions to be performed by the specific remote vehicle and by the local vehicle.
