Presumably not often from tarmac highways, though!
The most lost I ever got was relying on a paper map, up some hills in the Lake District, when the fog came down and hid any landmarks I could use to orientate myself. I'm also 90ish% confident the map contained some sort of error - possibly out of date due to water washing a path away, but that map was still on sale in a local shop and you'd hope they'd withdraw it if they knew it was dangerous. In the end the phone GPS app (on Symbian, which hints at how long ago it was) got enough of a fix for me to combine it with the phone compass and retrace my steps back to the tarmac.
The things is, if you want to look at where that path on the left goes, and how it fits in with other paths, you will see that best if you are looking at 10cm x 10cm or something like that, getting an overview without losing detail. That is where the paper map is strongest. Any device with a screen that big is going to be a burden to carry and a drain on batteries. And a pain to try to read in sunlight.
The ideal combination for walking is GPS, paper map and (for remote locations) compass. On a bike the ideal combination might depend on whether you are cycling alone. When I tour with my wife one of us will have the map on the bars, the other will have the GPS, in a bag or on the bars. And most importantly, of course, you need a brain that will sort out the mess if the paper map and the GPS map are both wrong, as sometimes happens. Adds to the fun.
