I'm not going to stop and help someone whose car spun out.
That sounds very serious. Why wouldn't you stop to help them?
I am in a rush and don't want to take the time.
It is your prerogative, but it would be good to check on someone who was in a car accident. They could use your help.
That would be very tiresome. I'd rather be on my way.
It would definitely take time out of your day to check on them, but think about how you would feel if you were in their shoes. I'm sure you would want someone to help you if your car just spun out. Also, if someone sees you stop to help, it will encourage other drivers to do the same.
