Last week, the California DMV gave General Motors permission to test its Cruise fully-driverless cars on the streets of San Francisco.

But based on footage of the cars in action that Cruise itself uploaded to YouTube, the vehicles may not be ready. As Jalopnik reports, the videos mostly show driverless cars following the rules of the road. But there are numerous troubling moments where the cars drive erratically or nearly cause accidents, calling into question just how safe it will be to leave them unsupervised.

To be clear, the video footage is about 10 months old and most of it shows perfectly fine driving. But, as Jalopnik argues, it doesn’t matter if a driverless car does its job 95 percent of the time when you’re the person in front of it for the other five.
