ssg, really mate, how do you get out of bed in the morning? The shower head might fall off and knock you out. Or, is it even safe to sleep at night, you never know what might happen.
Seriously though, you seem to have a very vivid imagination, only you haven't considered the flip side, what if your brakes fail, the thrust leavers stick open, your brakes catch fire and ignite the fuel that you didn't know was leaking. All this happened after V1. Wouldn't you rather get airborne, and have the whole runway to stop in (by which time someone will have told you that you're leaking fuel, so you'll make an informed decision of what to do upon landing)?
