Scenario. My Wife, kids, in-laws, and sister in law's family are all away for a long weekend. I couldn't make it, had to stay at home. They drove in three separate cars. 4 hour trip to get there. My father in law appears to have had a minor heart attack. This was late last night, I have not heard anymore from my wife upon waking up this morning. My potential predicament. They want me to drive 4 hours in my car, leave it there, drive my in-laws car home with them as passengers, then go back at a later date with my wife to collect my car which for me would be two separate days of driving. My mother in law can drive, has been for 30+ years, and it's her car. She would have my father in law as a passenger as a minimum. I feel this is unnecessary when my mother in law, who maybe doesn't like driving long distances, should just get on with it for once. She's 58 and perfectly capable, it isn't like she's an OAP.
