Gone are the days of fully analogic hitch hiking.
These days, the dreams of on the road digital connectivity have become real.
This means you can blabla ( allusion to some ride sharing app ) your way out of any knot, of any place you would end up stranded for all too many hours.
One might call this the "BlaBla Multimodal Strategy"
Using hitch hiking in conjunction with ridesharing.
It might still be challenging at times to find last minute ride shares, yet worth the try when ending up stuck, as to get back on a highway petrol station, or overcome a dense highway knot ( or a megalopolis ) to end up on a road / petrol station that has somewhat more unidirectional traffic and continue one's journey.
You might even find free peer to peer ridesharing apps or sites to help you out
or a variety of more mainstream commercial apps, depending on the region you are in.
If traveling moneyless, or without smartphone, this strategy becomes more challenging. But could still be done if prepared ahead, wiht a driver you get along with, if this driver is willing to enable you to use their smartphone for logistics, and for paying for it.
