A computer includes a processor and a memory, the memory storing instructions executable by the processor to collect biometric data of a vehicle user, identify a set of user-specific data from one or more stored sets of user-specific data based on the biometric data, and receive a request for a stored location. When the biometric data of the vehicle user match the stored biometric data, the instructions include instructions to display the requested location. When the biometric data of the vehicle user do not match the stored biometric data, the instructions include instructions to identify an offset location based on the requested location and a population density of the requested location and display the offset location.
