Even if nothing gets pushed through the courts, I think it could easily be a scenario of community shaming. We can all connect the dots, even if the person can deny it and be on their merry way. I think this is WAY worth pursuing.
What if this person was driving drunk? And what if they already have a record and similar incidents? Then I believe a case could be made as beyond reasonable doubt the suspect is guilty and held liable. For those of you just saying process the claim and continuing with your life, I half think you've done some stupid s**t like this in your life.
If someone is endangering people on the road, show some responsibility and at least make an effort to hold some one accountable like this BoostinChick is doing. As one great philosopher once said, "Com'on Man!"
