No matter what we do or say but there is no justification of speeding.
There was a research done in some city regarding the ambulance using sirens, speeding and ppl giving them way. They found out that with the sirens they actually saved about 43secs. That is 43secs with the sirens.
My conclusion is when Allah Wills Everyone Lives, and When Allah Doesn't No matter what you do, nothing will help.
