For a vehicle at a first location, a blind zone is defined that is outside fields of view of available vehicle sensors. A path is determined that avoids the blind zone and moves the vehicle away from the first location. The path includes a straight portion having a first end at the first location, and a turning portion starting at a second end of the straight portion. The straight portion is defined such that, at the second end of the straight portion, the fields of view encompass the blind zone. The vehicle is determined to operate along the turning portion based on obtaining sensor data from the blind zone upon reaching the end of the straight portion.
