I think all Auto owners have done this one time or another, only happened to me last Thursday out side Aldi, when i came tried to start the car nowt, nothing no clicking or lights flashing, just turn the key silence, for about 3 minutes i was confused then looked down at the gear stick it was in drive, i must have pulled up handbrake on turned engine off before putting it into (P) so left it in (D)
I had a smile on my face as i realised
