Do you drive around on the road to get batches?

Usually I sit around in the parking lot to get batches and am able to average $170-$200 per day but I was thinking about it recently and I feel I get shown more batches by the algorithm driving down the road close to stores than sitting in the parking lot. Do any of you just do highway sweeps to get most of your orders throughout the day or do you just sit in the parking lots mostly?
