I pack my cameras in a Domke F2 original bag. I further surround them ...in the compartments...with soft, Frank brand, general purpose foam sponges. I then seatbelt the camera bag in the backseat of my vehicle if I have a passenger or in the front seat if I'm by myself.
I don't connect the cover clips. I can pull the camera out of the back in seconds...when seconds count.
They ride on the vehicle seat...my K-1 manual talks about keeping vibrations to a minimum. Depending on the vehicle, vibrations and some ride harshness can be picked up on the vehicle floor, much less so in a seat.
I belt them in securely as otherwise...hard braking or quick emergency maneuvering...or...an accident can send them about flying in the cockpit. Think of a pinball machine and how the ball bearing moves.
Not good for either passengers or cameras.
My methods have been developed over years of experience, some of it not so good.

I never carried expensive camera equipment on a motorcycle. Too much vibration, too much road harshness. The one instance where use of a cell phone camera is better than a DSLR....carrying on a motorcycle.
