When we bought our 2018 Mazda CX-5 last April, it came with all sorts of tech and safety nannies, and I wasn't so sure about them. Honestly, I've come around on a lot of them. I spent a lot of time this year piloting the car in and out of the city when the wife was sick, and I was able to sample all of the tech for long periods of time.
Blind spot monitoring: Thought I'd hate it, but I don't. It's very helpful, especially navigating on crowded highways. It saved me a few times!
Impact warning: This one works, but if you have someone turning slow in front of you, the car starts freaking out, even if you aren't in danger. That's annoying!
Radar cruise control: It's really nice. You set a distance of how far behind the next car you want to be, and the cruise automatically adjusts itself. I dig it.
Backup camera: It helps more than I thought it would. It also helps in crowded parking lots when people are walking around aimlessly stuck to their smartphone screens and aren't paying attention to cars backing up.
Heated seats: I've had this in other cars, but it's nice. I want this in my next vehicle. Cooled seats are similarly... well... cool. Heated steering wheels? Only experienced it once, and it was weird.
LED headlights with auto high beams: My eyes have gotten worse with age, and driving at night can be tough in certain vehicles. These things RULE. Auto high beams work well, but sometimes sign glare or some street lights will trigger them to shut off, which can be annoying.
Auto wipers: Not a fan. It never seems to wipe when I want them to. Never seen a car with this that works well.
Bluetooth infotainment: This is great. It not only keeps phone calls hands free, but I can stream music with good sound quality as well. Hard to find a new car without it now, but all my older stuff (and future older stuff) will be retrofitted.
Traction Control: This can be a mixed bag. It's fine in most situations, but some cars are completely useless in snowy weather with it turned on. In my Mazda 3, it completely cuts power so I can't get traction in the snow, so it stays off when the white stuff is on the roads. As long as you can turn it off, I'm ok with it. I haven't gotten into a situation with the CX-5 where it's negatively impacted driving.
C/N: I like fancy tech. It's not all bad!
