The driver 'accidentally' turned, with speed, off an arterial, into the protest street, and despite having clear visibility of hundreds of people in his line of travel, kept driving, with people scattering out of his way.
He stopped when he hit a blockade, shot at one person who tried to open his car door, waved his gun around (With extra magazines jungle-taped together), and ran through the crowd directly into the police line. So much for being lost and confused, he seemed to know exactly where he was.
He was either planning a mass shooting, and lost his nerve at the last second, or was trying his damned hardest to provoke an attack on himself, presumably so he could respond with violence.
For an exercise - you try driving your car into a line of right wing militants protesting (or into a police line), and then shoot one of them. I doubt you will succeed in running to a line of safety, and I doubt their press will describe you as lost and confused.
