Not quite curval. If you are speeding and lose control of your car, you are responsible if you hit someone that wasn't doing anything of the sort. This would be an example of negligent homicide or manslaughter should someone die.
However, should you both lose control of your car and hit eachother, it's a pure accident and no one is at fault.
Should someone die from this, it's very unfortunate, but there would be no one person to blame.
