Without the toneau cover for the boot area, how do people go about it? Tint the back windows to maximum darkness and hope that no one can peeks inside to see if there is anything valuable?

Planning to pull the trigger for this car, but this is one of my concerns....hmphhhh

I guess I'm so used to throwing my laptop bag into my current car boot after work. Will just leave it there in the car while I go to a mall for shopping or dinner.

But with the car boot exposed in the CX-8.....
Is there any after market solution for this that you are aware of?
