I’ve found that new tyres have no grip at all in the wet for the first mile or so. Maybe Big places like Costco have had people lose control as they leave the car park.
And maybe that’s another reason of ‘running in’ a new car. I used to do the safety checks on brand new Fords, when I was an apprentice, and new tyres were always a concern for the very reason that you just mentioned. EVERYTHING on a new car, has a breaking in period.
Can't think that I've ever bought a complete set of four new tyres in one go (thankfully!) so it's always in pairs..... (except on my rather ancient previous daily, where at one point I had four different makes of tyre, all different ages but I'm slightly better paid now!) but certainly on the volvo the garage always puts the new tyres on the front and (if necessary) switches the older ones to the back. Is this because it's front wheel drive, or because it then steers with new ones? As the camper is split between rear wheel drive and front steering.... oooh which is more important to have the newer deeper tread? Interesting.
When the garage put four new tyres on my bus, it was all over the place. Having said that, they had inflated the fronts to 45 psi but I'm now wondering if the shine on the news might have been a contributory factor.
I was told the decision to always put new tyres on the rear, wherever possible, was due to a blowout happening on the rear axle being far more dangerous at speed, due to unexpected rear wheel steer caused by the deflated tyre, than on the front axle. Therefore, to avoid unnecessary litigation car tyre fitters put the newer tyres on the rear axle. Not that a new tyre is any less likely to suffer a blowout than a older one in road worthy condition, but that if a blowout did happen and then the driver would be unable to litigate on the basis that the tyre fitter didn't put the "better" tyres on the rear. Edit: So while I agree with @vinnyboy about sliding around in new tyres, and have experienced the same attitude at Costco, the real reason is, it simply removes the opportunity for litigation, probably from clever insurance companies. Tho, I also could be talking cobblers. Wouldn't this subject would be a great topic for the gameshow where 2 out of 3 of the panel are telling stories and the other team has to work out who is telling the truth?
Every tyre I've had replaced has been replaced on the hub it was removed from unless I've specifically asked for them to be swapped around - Maybe I just use sheeet tyre shoppes . Saying that, lady Lasty got the tyres replaced on her Beemer by the Kwik fit idiots and they put them on backwards, I took it back two days later and they accused me of moving them around the car - tossers .

New tyres should be fitted to the lightest end of the vehicle, which in nearly all cases is the rear, mainly for their better resistance to aquaplaning. Our vans are not that much weight difference either end, so it is no so important, but a Beetle you would fit them on the front.
I always thought a that a blowout on the front at speed was the more dangerous of the two - almost total loss of steering would be brown trousers time.
Are you sure? I parked the front of one right on my foot wearing trainers, I wouldn't fancy the same with the rear.
It's not so bad, it stung a bit. Across the foot in 3 moves - 1 to get it parked there, then 30 seconds while I figured out how to escape and that I couldn't let the handbrake off to do so.
Buses I've bought to keep have all required 5 tyres at once. I know I should swap them about including the spare, but I CBA - I've never managed to wear any out or had to replace because of cracked side walls. The Golf on the other hand ate tyres, it felt so safe to just slide a bit around every corner as it just went sideways.
