Perhaps it's time for Negril to consider improving the transit system in place then, if the only SAFE solution for visitors is to take private cabs, that's not a solution, it's a bandaid and results in only a few "reliable" cab drivers being used.
Why is it so hard to have set prices for the services rendered? I would NEVER run a business where I was not upfront with my customers about the prices for services/products rendered. If cab drivers want to be taken seriously they need to set prices that are easy for customers to understand instead of hoping that the customer doesn't want to negotiate their "stated" rates.
I would say about the same percentage of people visiting the DC area region that are familiar with the taxi cab system, zones,bus systems, or whatever mode of transportation they choose to use.
YES, there are risks associated with each transportation system, that doesn't mean they should be considered UNSAFE to use by visitors. People get mugged on buses in the US, that doesn't mean I won't advocate taking a bus because the inherent risk is minimal once you put it in perspective of the number of people using said transportation systems.
In my opinion you're throwing the baby out with the bathwater by saying route taxis aren't safe based on "incidents" that are newsworthy, they're newsworthy because they are NOT an everyday occurrence.
Please consider it logically, even if every single person visiting Negril uses private cabs it will just "force" the bad apples to change how they operate, instead of being robbed in a cab they'll be robbed waiting for the cab.
The "Lilliput" cab was most likely stolen, even if it was a Negril cab locals or visitors would not necessarily be safe knowing where the cab is from.
How many incidents would you say have occurred on the entire island in the past year out of the 3 millions of visitors to Jamaica?
