Dave if you relying solely on that alone then sure but in my case my car is set up with kill switch to ignition, fuel pump kill switch, battery isolation that kills everything and fuel pump cut off on no
oil pressure.
All set up with the help of Stokel Motorsport and Ozvenom so I'm pretty confident in its configuration.
The first part of my comment was regarding instant kill as I've mentioned so you can forget an inertia switch saving u from much before u hit it.
Moving on.....
