A computer includes a processor and a memory storing instructions executable by the processor to actuate movement of a vehicle at a first speed, identify a potentially available parking space in a vehicle direction of travel based on data received from at least one camera, then reduce a speed of the vehicle to a second speed that is less than the first speed while receiving data from at least one proximity sensor about the parking space, and actuate movement of the vehicle to a parking position in the parking space upon determining that the parking space is available based on the data from the at least one proximity sensor.
