It would confirm that it's the right answer for that child, because apparently she is willing to do stupid things at the suggestion of her friends.

My 15-year-old got our car up to 100 somewhere between Burley and Twin Falls on our way to Boise for the bowl game. I didn't know it at the time, but on the way home he was driving and I noticed he had it around 90. I just said to watch your speed, and he laughed a little. I asked what was so funny, and he sheepishly said he had reached 100 a couple times on the way to Boise. Doing that on a highway where the speed limit is 80 and everyone is doing 90+ is quite a bit different than doing it on a surface street with a 40 limit.
