In Ireland Public service obligation .As in we are obliged to provide the service as taxi drivers we have no such obligation to provide any service unlike the 54a bus which must run full or empty ...In essence, Public Service obligation was designed to help fund the cost of services that the market, left to itself, would not provide..TAXIS ARE NOT PUBLIC SERVICE VEHICLES .NEVER WERE NEVER WILL BE .But dont let that stop the stupit pricks looking for them to be made PUBLIC SERVICE and then any town or village or area or street without a taxi can demand one and who knows the minister might even lift the Moritorium or even approve rideshare .
