It depends on whether people disappeared while driving! Then their cars are just sitting there jamming roads!
That is an interesting variable. For the purposes of this thought experiment, since you’ve awoken with no idea of what happened to anyone, I think it is safe to assume the disappearance was sudden, and affected those who were driving at the time. I will however, for the purpose of granting freedom of movement, say that they disappeared between the hours of 2 and 4 am local time. In my experience these are the least populated times for roads, so there would theoretically be less congestion when you arose, at least in your area. If you somehow managed to make it to a radically different time zone then obviously you would experience the normal levels of congestion left by commuters and such.
