OK, here is the story. My DD(17) was invited by her friend to go to Six Flags over Spring Break(just a day trip). There should be 7 people all together, they have a big car. I was OK with that, I was taking girls to Six Flags before(much smaller group) and I would trust another parent drive all the way(4 hours total if no traffic). Yesterday, my DD told me that instead of father, girls brother (19 or 20, not sure) will drive. Now I am in doubts. The road has 70 miles limit and many cars drive even faster. I am afraid that a young boy will be distructed by all the OMGs from 6 girls, I could barely stand it when I drove them and I am not sure how long he is driving and how responsible he is, esp. on the way back, it will be dark. What do you think? Am I unreasonable or make sence. Would you let your child go on such trip? Please, I need some opinions. Thank you.
) anyway the first year he has a restricted DL which means he cannot drive after 11 or 12 and he cannot have more than 1 other teen passenger in the car. 
I do not think her parents will allow car to leave this way, I hope. It does not really mean the boy is air head too but I cannot really say anything. I can call and ask about how many years he drives and what kind of car but does it change the fact that girls will talk a lot and he will be distructed. I told my DD yesterday that I am not comfortable, she did not scream
but was upset. I really do not want to make a trip to Six Flags, I drove kids in August and really hoped this time will be another parent turn to suffer.
