I drive about 20K a year right now with probably 12K of that highway driving. I run up and down the East Coast from upstate NY to the Wilmington NC area to visit my father about every other month. 750 miles one way. My work commute is about 12 miles round trip.
For the work commute, I don't need the ASG at all. Maybe the emergency braking for those times we have ALL experienced when something distracted us and the stop was a little too close for comfort but no need for any of it if driving back and forth to work and running errands.
On the 750 mile trips:
1. ACC is a must for me. It is probably my favorite. Running up and down those stretches of 81 or 95 it is really nice. For me in this driving scenario, it would be a deal-breaker.
2. Lane Keep assist is ahh...ok. I could live without it if it wasn't there. It does remind me to put on my turn signal for those times I forget
3. Blind spot monitoring I could also live without it.
I would say if you travel a lot of highway miles it is very nice with the ACC having spoiled me. I don't look at them as driving aids as much as comfort features on par with heated seats and steering wheels. If used as intended, like a radio, they shouldn't interfere with your driving ability. If you put on ACC and read a book..well..you're not supposed to do that.
Now for all the "Old Timers" and that does include me at 58. I've been driving since I was 15 (yeah one year illegal) so that would have been 1978.
We really don't need any of the comfort and convenience items! I drove a 48 Ford pickup for 4 years with no radio, no power steering, no power brakes, no air conditioning, and barely a heater! The gas tank was in the cab behind the seat. Why waste money on putting it anywhere else? If you are a good driver then gosh darn you shouldn't have an accident and it's fine there! Power steering and brakes?? For babies. Air conditioning? Come on toughen up? That 48 had a nice big vent in the hood. You pulled the lever it opened up and blew all the dirt and crap on the floor up in your face. Kept you alert! Heater and heated seats? Can't be too comfortable you might fall asleep. Radio and subwoofers? Hell, just another thing to distract you. Rip out that radio and pay attention to the road. Power windows? I was lucky if they rolled up and down on that ole Ford! Took two hands to crank em! Blackout packages and 35 tires? What a waste of money.
I say all this in jest but everyone draws the line at what they think is needed a bit differently. I love to drive and I love tech! I don't miss double clutching in that ole 48 Ford and the rear sliding window is kinda nice in these new-fangled trucks of today!
