As you can see, Cook lines his car up on a divided highway without a traffic signal during what seems to be a fairly busy time of day—something that wouldn’t exactly be uncommon in most urban or suburban areas. His car waits and waits for an opportunity to turn left between bursts of traffic.

The left turn isn’t a difficult one for most drivers. If a human were in charge, we’d likely put the pedal to the metal as soon as there was a break in traffic. But Tesla’s Level 2 driver-assist technology isn’t designed to do that.

Instead, the car just kind of waits in limbo until it deems the moment is right, which it will only do if it decides crossing is safe. So that means it just kind of... takes off. It doesn’t give Cook a warning. It just goes. And as you can see in the clip above, Cook doesn’t always deem it safe to do so, which means he needs to be on high alert to grab the wheel or hit the brakes. It kind of negates the whole purpose of it being a driver assistance program when the driver has to be more alert than normal.

This comes just after last week’s video showing the absolute chaos that’s going on with Tesla’s Full Self Driving Beta program.
