We never wanted to release the capability to do a single pass to begin with because it makes bad data. We highly recommend using at least 3 passes for any linear job and even then you will need a lot of overlap for it to turn out well.
If the images are oblique there may be an issue with your gimbal if it is not remaining nadir during turns or changes in speed.
The overlap reports being off are a function of there only being one pass.
Your overlap reports look awful green... You need more along track overlap to get that to turn blue.
We have lots of customers that are mapping roads. Usually there is no reason why you can't use more passes.
