I’m also a millennial, and I think it depends a lot on rapport as well. If you regularly talk with someone in text form, and consistently use punctuation, it probably doesn’t come off as passive aggressive than if you suddenly respond with the trailing period. It also probably makes one-word responses a lot more abrupt.

I agree with above, replying “Cool!”, or “That’s cool!” would likely go over much better in that context

Yeah, the problem isn’t that the big trucks exist. There is a place for them, always will be. But they shouldn’t be a commuter vehicle, the majority of owners never use them for their intended purpose, and even those that do need a truck rarely need one of the size they get.

I do want to add in that driving slowly isn’t safer, but driving predictably is. If it is easier for you, driving slowly is fine, but be sure to use directionals and other signals to indicate intent to other drivers, make sure to follow the signs and rules of the road consistently, and be aware of the other cars around you who may drive eradically if they are getting frustrated.

Being able to multitask well is fundamental with driving safely, and keeping your speed low is one way you can reduce that mental load. But driving slowly on its own will not do anything to keep you safer. (Rather, low speed collisions are safer, but driving slow won’t necessarily prevent collisions or accidents on its own.)
