One example of how excessive time travel shows carelessness is the uncertainty of where the Time Traveler will land, when he arrives in the future. Even the Time Traveler express fear that when he comes to a stop he may crash into some object, causing a huge explosion. The Time Traveler may also end up in an ocean, and sink to his death. Another example of this is that the Time Traveler does not know anything about the future species. There may be bacteria and diseases in the future that are unknown to his time period. There is also uncertainty about how the future beings will react towards him. They may have shown him hostility rather than generosity.

One scenario that expresses the carelessness of the decision is that, the Time Traveler might get stuck in the future and will never be able to return home. When his machine mysteriously goes missing the Time traveler has no means of going back to his time. Having enough trust in the future beings, that he just met, to leave his machine alone for a whole day shows carelessness.

A last example of how time traveling really far into the future was a bad idea is when the Time Traveler almost gets captured by the Morlocks. First of all, he does not know what these creatures are capable of and what they might do. Next, he runs out of matches, which is the only way to keep the Morlocks away. This shows that he is not prepared to go against the creatures. If the Morlocks had caught him he may have experienced fatal consequences.
