I think you don't understand what bail really is.  It is an amount of money you pay so you don't have to sit in jail while awaiting trial.  It allows the accused to go about their life with minimal disruption, it helps to keep jail overcrowding down and allows the accuse a better chance to plea their case.  if a person has minimal to no prior criminal history and has many ties to the local community they are considered a low flight risk based on that and the seriousness of the crime committed , bail is set accordingly.  Failure to render aid is not that serious of a crime, however if it is proven he was DUI then here comes manslaughter charges and the bail will then be increased.  it is not the human life they putting a value on.
