Yep sometimes people need those real near misses to remind them.

When I was learning to drive I was very careful about checking each way and blindspots before doing anything. After about a year I was pulling out of a gas station one morning and there was a truck blocking my view to the right. I got complacent and I thought well I dont see any cars and I rolled forward a bit about to pullout and behind the truck was a car going 60km. If I'd pulled out I would have died.

Now im extra fucking careful to make 100% sure I'm pulling out safely.
