Thankfully, Subaru makes a very safe vehicle and he was not injured. The Honda driver did not stop after the crash to see if he was okay. This happened this morning in Grand Rapids, MI.
Edit: I completely agree with everyone’s assertion that he was following too close and was driving stupidly. I will also admit I have done the same on occasion, and have no expectations of being wrecked for it.
The primary issue at hand is that brake checking makes the driver feel self justified and because the law would say my friend is at fault, they see nothing wrong with doing it, and yet things like this happen and it is quite clearly very wrong.
