What I do (and what I taught my children to do) is look for occupants in parked cars, look for smoke or vibration from exhausts, look for steering movement in the front wheel; essentially look for any sign that suggests a door might open or the car might move out into the traffic.
So far I've been lucky.
I do all that plus the use of primary, I was doored in the mid sixties when I was a teenager, the memory is not a pleasant one.
