Taxis literally refused to take us after arriving in Budapest because we speak Hungarian and one of us studied there so had the Budapest accent too and everyone of them was all of a sudden busy and waiting for someone (they were literally just standing around smoking)

The original commenter was complaining about privacy issues with ridesharing apps, so I am not sure what cell signal has to do with anything? Having gps on is literally useless unless you check your google maps or waze or something that you are not taken on a ride around and all of those track you so have the same privacy issues as alluded to by the original commenter I don’t think I can make my point any clearer.

Also if you think this doesn’t happen in less developed countries then you are extremely naive.
