Driving is terrifying.
At any given moment on the road, you're just inches away from having your car crumpled like a beer can with you and your loved ones inside. The most terrifying thing about it though, is that it can happen to you at any time. You could be obeying every law on the road, and, bam! A semi appears where it shouldn't and you're almost a goner.
Thankfully, there are dash cams seemingly everywhere, so we have plenty of footage to haunt our dreams at night and escalate our anxiety.
