A lot of folk just want to get from A to B. As a bespoke service there ought to some form of quality control...
Getting from A to B is a bespoke or specialised service. And there is a cost to that. And there is QC - the entrance exam, the LRA, the 10 yr rule. Maybe not the strictest QC but it is what it is.
We had a vibrant hackney service driven by men that served their communities, providing a real alternative to car ownership including in areas with scant bus services.
Dare I say we're priceless

It's things like this that make it worthwhile keeping the sPSV structures in place. For these passengers (and lonely bachelors), I would suggest they're happy to pay the local rate which everyone is happy with and not change driver for a euro or two. It's not all about the money?
If rideshare or Uber-style pricing gets a foothold, it's precisely the rural areas that will suffer. The current driver knows he'll get his local fiver/tenner runs all day long but if Uber gets in, they'll want their money first and then add on a few pennies for the driver and it'll become too expensive for the locals. Instead of ' taxi driver Bill' who the bachelor farmer has known for 10 years & trusts, it could be student Nath driving his mammy's car. And he may or may not still be high from the student Thurs night blowout up in his University town.
I know you don't recognise such economic theories as the price elasticity of demand but, believe me, there's a reason the rideshare platforms offer discounts and there will be consequences when they stop financing those discounts through subsidies.
I'm well aware of price elasticity. I keep an avid eye on my Amazon wishlist* because I know the prices they charge yoyo like crazy. I arguing that price is not the
only factor. What I'm suggesting is the NTA take a wider/longer view than the next fiver. If price were the only metric, why bother making us buy expensive WAT's or buy fire extinguishers that don't benefit the passenger? Or making us take the extra 5 mins to get a blind person into the taxi. We're a Public Service afterall and the Govt/NTA need to take that into account. Story in today's paper saying pharmacists can now charge for some of their advisory services. €30 for the pharmacist or €70 for the full-fat doctor. The Govt made the decision that these prices are in the national interest and for the good health of the people. Why not do the same for s
Public
ServiceV's? No point in doing a biannual fare review if it's not worth the paper it's written on?
And I do give discounts. I'll often round down to the nearest sensible number but frequently, the passenger will often round up the same fare to their sensible number. And I think you've said it yourself that your taxi save passengers often tip, which doesn't make economic sense if lowest price was their primary motivation.
