I go out occasionally with a friend who I like very dearly. We're both nearly 50. However she has this habit which scares me a bit. She doesn't drive so I always drive. But whenever we arrive at our destination she swings passenger door of car open to get out whilst the car is still moving to park up. It means that I have to finish driving with the door wide open to park properly. This puts extra stress on me to nail parking the car in a space in one attempt.
I feel it would be telling her off to say don't do it, but I just find it dangerous, not to mention the car starts beeping like crazy as a warning that the door is open!
How can I politely advise my friend to remain calm in seat with belt on until the car has come to a complete stop and the handbrake is safely on?
