Unfortunately the motor industry is one of the big bastions of imperial units in the UK. I believe that they very much like the idea of Ireland having km/h and the UK having mph as this enables them to segment the market making it unattractive for British motorists to buy cars outside the UK, enabling them to push British car prices as high as they can get away with without British motorists going elsewhere.
I believe that new cars in Ireland attract a fairly hefty tax which is not payable by non-Irish residents. This means that car manufacturers have got to drop their process in Ireland to make their mid-range cars attractive to the Irish market. British buyers are able to buy cars In Ireland at Irish, get the Irish taxes refunded and then pay British taxes when they are imported into the UK.

SI changed to Pascal as the unit of pressure, you choose the prefix to suit the value, aircraft use hPa because it's the same number of digits as millibars, but kPa is fine for most atmospheric pressure, this is what the Canadians use for weather reports on TV. Over here in France (and I believe the rest of Europe including the UK) they use hPa for weather reports. An interesting aside, I was driving back from the airport the other day and passed a line of Army Land Rovers, I thought they were probably French, but passing one I saw stencilled on the spare tire holder 60 PSI, so I figured they must be British, although I would have thought the British military were entirely SI by now.

I see on the list millibar, Hg, Pa, bars, mmHg, psi, atm and kPa. Now, since I know less about Pressure Units than most of you, I am hoping someone would jump in and recommend the most appropriate one. (I already know that none of you will recommend psi.) Thanks in advance. See attached picture. I hope none of your computers have trouble opening a png picture format.
