The brakes maintained there effectiveness without losing vacuum, while engine off coasting / in gear for braking.

I feel like the kill switch really is necessary, It is risky to be fooling around with the keys while driving plus there is a possibility of turning the ignition key to far, unknowingly locking the steering wheel.
I do not engine off coast every chance i get now because of brake issues and the key issue.
With a kill switch & in gear braking i could engine off coast in a lot more circumstances, such as shorter coasts with the convenience of the kill switch and steeper hills with the in gear braking ability.

Piwoslaw i am going to look for the crankshaft position sensor. What does the motor think happened when the switch is opened ? it sounds unconventional but effective. I like it.
