The BACK Seat!
There have been countless incidents when an AD patient grabbed the steering wheel or switched off the ignition by taking the keys — which immediately locked the steering wheel! Less dramatic is their penchant for sometimes toying with the radio, heater/air conditioner, etc .

Getting In The Car
At some point many patients lose their ability to conciously do certain things, and getting into an automobile is one of them. I”ve found that positioning the patient with his/her side to the seat, then putting your hand on their shoulder and guiding them into the seat while distracting them with a comment or question works well. The concious effort to get in the car may be confusing, but the subconcious can take over once distracted.
