The moment of panic and the lingering feeling in the pit of your stomach when you're driving and narrowly avoid what could have been a disaster.

Not even necessarily your fault, things like braking for a deer, or a car not seeing you in their blind spot and changing lanes into you and you have to hit the horn.

Something that reminds you that no matter how much time we spend driving and how easy it usually is, vehicles are fucking dangerous and you don't want to get careless. Something that reminds you why driving deserves your full attention the entire time.
