“Do you know why I pulled you over?” banned in California

There was a lawyer youtube channel that said they can't do this. They have to have a resaon and can ONLY proceed based on this reason. Example - if they legitimately stop you for speeding, they're not allowed to search for drugs or anything else unrelated to the speeding.

How do you look at someone funny when you’re driving?

And how did the Garda see you looking funny at them?

How did the story finish Padrepio?

So if there's a bottle of whiskey in your hand or a dead body in the back seat they must give you a speeding ticket and go on their way?

No

The Guard invited Padre out for a drink, Padre said yes, and now they are engaged to be married next year

A Garda can only pull you over if he believes you have committed an offence. The Road Traffic Act has loads of reasons, simple ones such as crossing the centre line, not indicating on time, too slow to pull away from lights, etc. The reason to be pulled over is many. Once stopped, questions can be asked and observations can be made. You are quite entitled to say nothing, but it doesn't exclude you from any laws/legislation you have broken, or what is subsequently observed during the stop.

From my own experience, I used to ask that question. If the person answered with the reason I did pull them over for, they were less likely to get a ticket (if applicable). They passed the initial stage of the personality test. The rest of the interaction will also determine the outcome. Gardai have discretion. Most don't want to be giving tickets to normal folk, but sometimes normal folk need to be reminded about the bad level of their driving. Anyone who answered with "no" or was aggressive/uncooperative, most certainly got a ticket. Nothing worse than someone thinking they did nothing wrong when they did, or thinking the minor law they broke should be allowed.

I had an elderly man get out of his car at me one day because I pulled him for going through a red light, clearly through it, and he adamant he didn't. He got a ticket. It'#s nice to be nice, and while it doesn't always guarantee you won't get a ticket (the offence really does matter), you've a better chance. Maybe not these days though, the public reaction to the ticketing "scandal" has basically guaranteed, imo, tickets will be issued regardless nowadays.

I believe you are incorrect.

I felt like it is not a reason, they must have reason to believe that you have already committed or are in the process of committing an offence.

If you can link the legislation that permits stopping a vehicle for no reason it would help.

Serious question- are the Gardai who aren't the most stellar students in Templemore the ones who end up getting sent to the traffic corps?

Like if you join the guards surely the ambition is kicking down doors, drug busts, bursting in bedroom doors with the old "get yer trousers on son, yer nicked" style of a 70s Cockney detective. Progressing to detective later on, calling your colleagues with a mock Glasgow lilt to tell them "ders bin a merder" in the best Jim Taggart accent (because such horrors demand levity to keep you sane)

Little boys dont really dream of standing by a rural roadside with a hairdryer catching some lad rushing to work who forgot to set his alarm when being a guard is their ambition.

For me the childhood dream involved having carte blanche to shoot people. Which is why I wouldn't have got in, along with my taste for recreational drugs.
