Er no, in the case of vehicles there is no such thing as an accident, somebody is always at fault. This is why the police call them collisions not accidents. In my opinion the sentence in this case is no where near enough. If you choose to drive that far above the posted speed limit then what do you think any reasonable person would expect to happen if it went wrong. Surely this counts as intent of some sort. Wrong person died in this case, imagine if it were a biker who was killed, would you have said the punishment fitted the crime then?
