I don't have adaptive cruise so the way I'm reading what he is saying basically :
Use adaptive cruise in heavier traffic situations where lane changes arent as easy.
Use standard cruise control when the passing lane(s) are clear(er) so they can pass at their cruise speed at leisure without either having to speed up or hold up traffic behind them to perform the pass.
Slower driving would also give more time for the other 'party' to react and adjust as well / potentially limit the injuries sustained.
But realistically yeah it doesn't make a difference because licenses are way to easy to get and keep (again usa - other countries may differ) and american drivers pretty much all have their heads up their asses 24/7.
Yup, it's just bullshit like trickle down economics.
The only people being affected by inflation are the people who can't afford to save money.
(Which one of the points of inflation is to prevent money hording)
The oligarchy hides most of their wealth in owning stuff and as such are unaffected.
Wine is a huge scam.
Sommeliers are just salespeople making shit up.
It's bullshit, you don't detect notes of 15 different things all mixed together.
