This made me think of something.
My grandma was determined that she wouldn't stop driving until she was dead, even though her motor skills and reaction time had decreased dramatically since she had turned 80. It was that last little bit of independence that she had left and wasn't going to give it up for anything. She had limited herself to little trips to the store, hairdresser and pharmacy, which were all under a mile away from her home.
She was having a relatively normal day, and had called down for a last minute appointment at the hairdresser; a 7:30 pm appointment, the latest one for the day at the salon. She arrived a little early, and parked directly in front of the salon. She was very well liked there, the staff enjoyed her company and from all reports an agreeable time was had by all involved.
At about 8:15 pm she departed the salon and the staff locked the door and wandered their way to the back room to go about their closing duties. My grandmother entered the car, started it as usual, fastened her seat belt and was about to depart for home.
This particular parking lot had a fairly high sidewalk separating the lot from the strip of shops. The front of most lower sitting cars would not actually clear the sidewalk, therefore there was quite a lot of chipping, dings and paint scratches at the front edge of it. It wasn't likely that a standard passenger vehicle would drive onto the sidewalk without some sort of deliberate force was used.
As normal she put the car into gear and began to depress the accellerator. The car didn't move. She sat puzzled for a second and pressed the pedal again. The vehicle just hummed in response. She did it a third time and once again all noise, no movement. Then, in frustration, she slammed the pedal to the floor. The car roared and lunged forward, onto the sidewalk and went crashing through the front doors of the salon. It didn't stop until it was a full five feet completely inside the business she had just left not two minutes before.
She didn't realise that the car was in drive and not reverse.
Fortunately, none of the staff was in the main area of the salon at the time and my grandmother escaped with just a bruised wrist. The car and the entire public area of the salon, however, were a disaster.
Within a couple weeks the salon was repaired and back to business as usual. Much to my grandmother's friends surprise, she still frequented the business. She was treated as a faithful regular and friend there. She had her hair done at least once a month at that establishment until she passed away about four years later.
She never drove again after that incident.
Priceless.
