This is what Darla Drentlaw wishes she'd shared with her kids and what you might want to share with yours. Sleep deprived, both Mary and Andy crash in the simulator. They're different drivers today. They're as impaired as if they were drunk. They are slower, they need more time to concentrate and their driving is erratic.
Errors come at lower speeds then yesterday.
There's definitely a difference from yesterday. For Mary, the crisis comes not with the squeal of tires, but when she simply fails to react at all. Their results are the hallmarks of a sleep-triggered crash. Katie Drentlaw didn't try to stop or steer either. You never fill the hole.
