I agree 100%. I have both on my Wrangler, and love it. I would guess I use Adaptive Cruise about 80%-90% of my driving with it. Everyone says they don't want something driving for them, or how fast of reflexes they have. It's called an "accident" for a reason. I'm I firm believer in anything that could save my or my family lives.I ordered the ASG on my 21 JLUR. I have it on my 20 Grand Cherokee and really love the adaptive cruise in traffic (live in the DC metro area) and the forward collision has also been a nice feature. It hasn’t had any false alerts and actually saved me from a collision once.
I was driving in traffic at about 45mph and am generally very observant. I was following directions on Waze and I glanced down to see the next turn and the vehicle in front of me happened to brake at the same time for a squirrel. Fcw bleeped and braked quicker than if I was to notice the slow down and brake. It was close but there was no incident.
So while people on here say how observant they are and they pay attention, accidents happen at that split second you look away. And everyone does it, whether to glance down at your speed, look at the name of a road coming up, following nav instructions, to itch an eye, etc. This is when adaptive cruise, forward collision warning, etc. are truly useful.
If you can afford it, get it, and if you find it’s too intrusive, dial it back to alerts only. It may just save you or someone else on the road.
