There was an incident just a few weeks ago where a 5-year-old in Utah took his parents' SUV for a joyride and managed to make it to the interstate before getting pulled over.

Based on the police footage, he wasn't doing a very good job of maintaining his lane, but he apparently managed to avoid hitting any stationary objects, so... go figure?
