Sorry, but if this is even on the same planet as reality, you're either in custody or on bail. Either way, you're probably about to get a psychiatric evaluation to determine whether you understand your rights, can competently participate in your defense, and whether you have any means of mitigating what will undoubtedly happen to you.
Reckless or grossly negligent conduct poses a more severe and obvious threat of death than mere carelessness or simple negligence. Recklessness and gross negligence can be shown in a variety of ways, such as driving under the influence of drugs or alcohol or violating certain traffic laws, like speeding, texting while driving, or deliberately running a red light. Ignoring a warning not to drive while taking prescription medication could also constitute reckless and gross negligence, and so could driving with a known medical condition that could affect your ability to drive safely. The extent of the danger created by the driver’s actions will usually determine whether the defendant is charged with simple or aggravated (meaning more serious) vehicular manslaughter. Aggravated felonies carry stiffer penalties.
Note that mere negligent (careless) driving will not result in a charge of vehicular manslaughter. For example, suppose a driver causes a fatal accident while going five miles over the highway’s posted speed limit on a clear day. Even if analysis shows that speed was a factor in the accident, this excess speed is unlikely by itself to support a charge of vehicular manslaughter, though it could be the basis for a misdemeanor.
but in the US, he is presumed innocent
