Even if you're the type that immediately jams the key in & flips it to "Start" there's still that millisecond where things try to power up only to be cut off from power again. That makes me cringe. I'm a get in, flip key to run, wait until fuel pump primes and other non controllable electric stuff stops thrashing and then flip to start kind of guy. So far I've lost/killed nothing doing things this way. The only car I didn't do this with is my Fury, which was analog everywhere so it didn't matter.
