You didn't mention how CO2 raises energy accumulation (heat) by lowering how much radiation is reflected back out as it has specific absorption bands that are outside of other greenhouse gases that don't absorb the same, causes ocean acidification, has a lifespan that's 2-3x longer than other greenhouse gases, and it's been emitted in record numbers only recently, creating anthropogenic climate change.

Get snow tires, made the mistake this year of not putting them on in December thinking a day of snow wouldn't hurt and regretted it when I was sliding down the hills. You can technically downshift in an automatic it just depends on your car, check the last options on your shifter or paddles on your steering wheel. Besides that, don't outright brake coming down just tap it if anything and going up you want a consistent speed so you're constantly digging in but you don't want to race up the hill. With proper tires it's all about practicing to avoid sliding. I was the same way coming from Florida. I'd also suggest a windshield/sideview mirror cover to avoid having to clean it every time

Was a couple bucks in change much of a hurdle before?
