The part of this story where a Tesla erratically changes speed and veers, even trying to steer out of a PIT and keep going, seems like it might offer some Autopilot clues.

The callers told the dispatch that the Tesla was swerving in and out of its lane, changing its speed drastically, and nearly hit other drivers, an FHP arrest report said.

A trooper pursuing the vehicle said the Tesla even sideswiped a concrete wall and began speeding up to 80 mph when the trooper initiated a traffic stop.

“The vehicle was driving erratically all over the road, almost striking other motorists, which highlighted the need to get the vehicle stopped urgently,” the trooper wrote. “I [conducted] a PIT maneuver to stop the vehicle, but the driver steered out of it and kept going. I was forced to conduct a second, more aggressive PIT maneuver to finally get the vehicle stopped at northbound I-275 milepost 45.”

Note these points:

• Police described the owner as “just confused about what was going on” as if not driving the car
• The Tesla reportedly “was driving erratically… almost striking other motorists”. Almost. Not striking them. Just almost.
• The Tesla sped up to 80 when police flashed lights to initiate a stop, not quite evading them but rather trying to move forward as if they had just cleared the road ahead. Likewise they described the first PIT attempt as “steered out of it and kept going”
