Exactly, buses and road traffic have higher accident rates than trains (and aircraft) and this has everything to do with how those means of transportation are being operated. Rail and aircraft operators are companies that take responsibility for the lives of a large number of people and that typically have a long term view, as in, they'd like to be in business in half a century or more.
Tourbus operators (not the same as public transport) are responsible for a large number of the road traffic accidents involving buses, public transport involving buses is involved in accidents at a much lower rate. The reasons are: tourbuses tend to go faster, drive much longer distances (exhaustion), drive routes that are less safe to begin with and so on.
The way the rail industry deals with a capacity problem on a line is not to send more trains with a decreased train-to-train spacing but simply to send longer trains.
You can't really make longer buses beyond a certain maximum length due to the fact that the minimum turning radius of roads is a very small fraction of the minimum turning radius of a train.
Thinking about it I guess the more relevant question is: can the "hyperloop" stop faster than a train? If not, why should we let them run at anything like the capacity Musk claims?
A train is not constrained in the same way that the hyperloop is. This is both a good thing and a bad thing depending on what happens. Presumably the remaining air between two hyperloop capsules will be compressed prior to impact reducing the deceleration to something more manageable.
