A new-ish, well-maintained vehicle with new tires, fresh oil change etc, if it's left dormant & undriven untouched in a residential driveway for 1 year, will it be driveable after 1 yr?
Only three things I can think of, two of which have been covered already:
Battery, ideally disconnected.
Gas, ideally add a stabilizer.
Tires, tricky, ideally you'd move the vehicle every so often by 20-30 cm to even the load, but worse case your tires are going to wear out quite a bit quicker after a year standing on the same spot.
Tyres go bad through the vehicle's weight, so either raise the vehicle enough so they don't touch the ground, or remove wheels and put it on stands.
Once you make sure the car is secure release the handbrake so it's not engaged for a long period to prevent it from fusing.
Clean thoroughly inside and out to make sure dirt doesn't adhere to paint or seats, that no food is left inside the cabin that can go bad and smells that can embed themselves in the seat foam etc.
Cover with a car cover to protect seals, paint, seats from the elements.
I suspect OP is asking about a vehicle where it’s not known in advance that this one year hiatus will happen, ie there’s a vehicle that’s already been sitting there a year.
