Yichud when hitching rides with woman

Is there an issue with yichud for a Single bochur hitching a ride with a Jewish/non Jewish married/unmarried lady in a locked car daytime/nighttime with tinted/untainted windows? Assume location is within a town or city.

Thanks in advance for your help

Does it matter if the car windows are tinted or the car doors are locked?

The general rule is that there’s no problem. However if the situation is such that a car passing by wouldn’t realize anyone is in there, that would be a problem.
