Vehicle backover injuries and deaths occur when someone, without a driver's knowledge or awareness, is positioned behind a
vehicle as the driver is backing out of a driveway or other parking spot. Most victims of backovers are the elderly and children.
2 To add to the tragedy of backover injuries and deaths, the driver is often a neighbor or relative. When a child is the victim, the
driver may even be the child's mother or father.
Since most of these heartbreaking incidents occur in private driveways rather than on the road, they are not typically included
- in traffic-crash fatality data. Therefore, experts often don't agree on the exact number of children injured or killed in backover
incidents each year.

In this excerpt, the author talks about vehicle backover injuries and deaths. However, as we read the excerpt, we make an impression that the data presented here is inconclusive, as the author doesn't provide the exact statistical information and base the facts mainly on his/her suppositions.

For example, the driver may even be the child's mother or father or experts often don't agree on the exact number of children injured or killed in backover incidents each year doesn't provide any relevant information from which we could make a certain conclusion, as the paragraph seems to be incomplete and inconclusive.
