Dude I don't think you get it. I intend on competing with the car at some stage. CAMS dictate that every vehicle competing in any speed event have a fire extinguisher fitted that adheres to the regulations. One of those regulations is that the fire extinguisher is mounted in a way that it accessible to the driver and crew without the aid of a tool.
I consider the boot latch a tool, at the very least if the car gets pummeled up the back the boot may not be accessible. What if my leg is jammed?
Besides, why just follow the bare minimum rule, mounted beside me in the cabin is the safest in my opinion as I can access it quickly, IF I NEED TO. It's not ugly sitting where it is, it's a quality installation and it adds to safety. What could possibly be the problem?
Besides you completely ignored the point I had about being able to extinguish a small under fire that could completely engulf the car if left to it..
