Why wouldn’t he crash it through the doors at speed?
Because this was a suicide, not a terrorist act. He didn’t want to hurt other people.
You see how changing the words changes the scenario? This was probably a guy who was suffering from depression and had gone through a hurtful break up. He just wanted to “end it.” I don’t think he wanted to kill other people. I agree withj those who said he was sending a message to the Ex.
