You do you.
I do me.
(sick of every go_____ned body refuting me...)
If an honest discussion with facts is everyone refuting you because you don't agree, sorry can't help that. Different conditions apply for different people. Refute the experts in car testing and most owners manuals and they will say to not us cruise control in wet or snow. Wide vs. narrow is again dependent on conditions, scientifically proven, Nokian has it in their website and many others. Narrow is better for loose snow and slush, wider better for dry cold ground when it's not snowing, so everyone is correct depending on most usage for that person.
I pointed out that I can buy the same size tire, factory size and can have multiple widths touching the road. That might help someone that gets a flat tire and looking to replace only 1-2 tires. A 1.3" tread contact difference between Firestone and Michelin is not a small amount and may affect handling a lot more than 4 narrower or 4 wider because 2 will be totally different going around a wet or snowy turn.
None of that controls your mindset and your heavy foot as you describe. My FIL has a note on his dashboard that says don't speed and stop FULLY at all stop signs. He needs to read that everyday or he won't and has gotten pulled over for rolling slowly through stop signs. He's retired and has no where he needs to be but still can't grasp the red Octagonal sign meaning otherwise. Him doing him.
Expert drivers and testing say to put best tread depth on the rear and shops will only install new on rear unless you sign liability waiver and even then might not. Some people say they don't know reality and will put new only on front. I prefer the happy middle and rotate my tires to keep within 2/32". I also buy 4 matching tires not 2 at a time.
I hope your day gets better and you can worry (or not) about more important things in life than people on an internet forum not agreeing with you. If you can't then consider counseling, anger management, road rage control, defensive driving, Yoga, meditation or shots of Tequila at your happy place or what does it for you to bring you back to have a good day.
