I don't know about your country, but people going to prison for causing road fatalities is extremely rare here.
Even temporary loss of the drivers license has a very high bar, and that's the main form of accountability for driver behavior in Germany, apart from fines.
Badly injuring or killing someone who themselves did not violate traffic safety regulations is far from guaranteed to cause severe repercussions for the driver.
By default, any such situation is an accident and at best people lose their license for a couple of months.
