Being stuck on the side of the road
I remember when I first learned how to drive my mother had a dodge. We had no idea what was wrong with this car. But all summer we were afraid to go any where far.
After a while when we were driving the car would over heat and just die on the side of the road. I wish we would have had some kind of automotive diagnostic software that would have told us what was wrong with the car.
I know that we went through many summers were the car would die at a stop sign. We would just move the car over to the side of the road and wait until it cooled off. It was so embarrassing. They never found out what the problem was, we just had to live with it. It was so nice when we finally got a new car and we did not have to worry about those issues again.
