I suspect not The rear window shelf is a dangerous place to keep anything but something like a blanket. In a collision, even relatively small thing there can cause injury.
You can't really see the trunk contours in the pic. It fits in the flat area that it's designed to, not edge to edge. It doesn't solve the problem of full cargo protection. Maybe weather tech or other aftermarket supplier will figure it out. Sent from my Pixel XL using Tapatalk
We can only hope. I got tired of waiting on WeatherTech and bought a large generic mat at Wally World and cut it to fit the area in front of the Honda trunk plastic one. It’s cheap and it works but it’s gray and has no raised edges to catch debris.
