Visibility while driving was really bad. The solid C-pillars on the Equinox, compared to the C-pillars with windows on the Blazer, made a big difference.
Also, the placement of the side mirrors was poor on the Equinox EV. We parked the Equinox EV, Blazer EV, and then my 2020 RAV4 in the same parking spot, with a 2500 HD parked directly and perpendicularly behind the space about two car lengths back. Through the driver’s side mirror, I could see from the front bumper to the rear taillights (but not the rear bumper). With the Blazer EV, I could see from the front bumper to nearly the back of the rear door. As for the Equinox EV, I could only see from the front bumper to about one-third of the way through the front door.
When driving around my town, I can see three lanes of travel about 6–8 car lengths behind me in my RAV4. In the Blazer, I could see 1.5 lanes of travel, and in the Equinox, I could only see about 0.75 of one lane. Same road, similar traffic density.
So both Chevys suffer from poor visibility compared to the RAV4, but the Equinox had exceptionally bad blind-spot visibility on both sides. The Blazer had adequate visibility on both sides but could benefit from larger mirrors.
