I have a 2017 Equinox with a 6cyl. We're very happy with it. I was looking at a Traverse, but it has the stop start feature and as you said, it cannot be shut off. Unbelievable. I'm hopeful that the next vehicle I get either has the option to shut that off or, more likely, it will be electric. Stop start on a gas powered car reminds me of a golf cart.
In driving some loaner cars with stop start, there are two things you can do. You can learn to creep. If the car isn't fully stopped with your foot on the break, it doesn't stop. I got pretty good at that. The other thing I've read that you can do is drive around in manual mode. Not sure how much of a pain that would be but it's supposed to work. I understand there are other brands that allow you to shut that off.
Another point however, is that if you're more of a country road driver, which I assume street is, it may not happen enough to matter. I live in the suburbs and stopping at lights and stop signs is very frequent.
