"Where is the evidence that DS killed herself, her children and her nieces "in a planned way"? On the contrary, we have testimony from opposing drivers that she was honking her horn to get them out of the way."
You need to look up and read the police report, which contains the interviews of the many witnesses who saw her that day. The horn honking she did that day was EARLIER in the day and was not on the Taconic. She was honking and flashing her lights when she came up onto the back of someone, then tailgated them and started honking. In several cases she attempted to pass people using the berm.
As to the actual event on the Taconic, first of all, when she started up the exit ramp there were FOUR cars coming down the exit ramp. They all swerved, blew their horns, waved, flashed their lights. She never swerved, never varied her speed, just continued straight on up the ramp.
While on the Taconic, Diane never honked her horn, is described as having both hands on the wheel in the "10-2" position (by several witnesses), and never swerved or changed lanes (by all witnesses who saw her) despite ALMOST being hit by several other cars prior to the crash. Other drivers were honking at her and several literally had to run off the road to avoid her.
I have no strong opinion about suicide/homicide vs. being very impaired. But based on the actual eyewitness accounts, debating the possibility of suicide is not outside of the realm of possibility.
