A cab service with unknown, frequently updated nodes where edge weights - driving distance from last drop to next pickup- can vary, would qualify as pretty bad version of TSP.

You can come up with a good enough solution but it’s not “solved”.

This “good enough” solution starts to break down whenever there is a huge concentration of drivers in a location. If this weren’t the case, ride shares wouldn’t have had to add a cancellation fee and hidden destinations from drivers.
