It's a stupid feature, but I can't see how Snapchat is to blame for the actions of a passenger. Is the feature designed to show off how fast you're traveling, sure. It wasn't the person in the driver seat trying to record though.

If Jason Davis was driving under an instruction permit, he did not have anyone in the car to legally supervise him under Wisconsin law. If he was driving under a probationary license there was a possibility he was driving legally if he was past the 9 month requirement without it being extended, but if he was still in the initial 9 month period he had more passengers in the car than he was legally allowed to have. It is possible for him to have been outside the probationary period of the probationary drivers license, but that would require him to get his license some time between Jan and March of 2016 and then immediately get his probationary 6 months after that with all the requirements entailed, and I find that unlikely.
This seems to me to be a series of bad decisions made both by the teenager behind the wheel, and the parents for letting him do so.
It seems similar to "Send Me to Heaven" [1] the app for gamifying the destruction of phones.

It wasn't like the parents bought their kid an Audi R8 or similar.
But somewhere in the 150-200 horsepower range will end up with a car that is very efficient at 70 mph, and a top speed around 130-150 mph depending on gearing an aerodynamics.
Of course, rather than designing cars with lower power, they could simply add a governor, so the car computer does not allow travel above a certain speed, but that would be an incredibly unpopular option, even among people that don't go significantly over the limit.
