I am not a car expert in any way, but many have said some of the newer cars will not allow you to shift into neutral or turn off the key when in drive and in motion. I would like to know if that is true, if so that design would seem to be a malfunction itself to me.
I have not tried turning off the key but I frequently shift into neutral when rolling down long grades (not supposed to do it because you have less control over the car but it saves gas).
The answer to shifting to neurtral is yes, at least on the 2011 I drive.
Honda CRV allows ignition shutoff while in motion- I did same right after acquiring my new CRV.
I was on highway at speed running on cruise control- hitched myself in to more comfortable position in seat- knee clipped ignition key- no more engine, popped into neutral, hit emergency flashers, pulled to side of road.
Calmed down for 10 minutes, arranged keys so that not possible to repeat.
