Same, both sets are left in the cloak cupboard by he front door, which to be fair we've only been locking for the past couple of years (yeah yeah I know).
The Mrs still often leaves her car unlocked, in the 12 years we've been here I've only heard of one opportunist taking a sat nav from a neighbours unlocked vehicle.
Were a cul de sac off a cul de sac so to speak so it's too far off the beaten track for an opportunist and the neighbours all have far nicer cars then me so whilst there's are on the drive mine is relatively safe I reckon.
There is an argument to leave them half way up the stairs in view, this means they are safe from some but those willing to come upstairs will get them before the shit hits the fan so to speak.
Read about so many hard men and what they would do and whilst I'm no shrinking violet it's an insured asset and I have far more to lose then them so they can have it.
eta, actually I did capture one incident on the CCTV, a neighbour was putting his trade waste in my bin when I put it out for collection.
