Recklessness is pretty serious when it comes to anything, not just driving.
A few months back, I was riding my bicycle down the usual route I'd take to college. From the countless times I'd gone down this certain path, I knew that it was nearly always empty.
There were warning signs around telling riders to dismount from their bikes before getting to the blind corner, but being the smartass I was, I chose to ignore this warning,
I slowed down enough so that if something did happen, it wouldn't cause much of a problem.
Instead of the nothingness I expected being around this corner, there was another cyclist turning the same corner and we were about to crash.
Thankfully we both hit our brakes at the right time and nobody was injured, but it could've very easily been a different story.
