How dangerous is travel in the United States? It depends on how you frame the question. If it's risk per kilometer, the U.S. has 6.71 deaths per billion vehicle kilometers of travel compared to the United Kingdom, which has just 3.56 deaths per billion vehicle kilometers. This makes vehicular travel in the U.S. about 88.6 percent more dangerous than travel in the U.K. If it's risk per year of life, the U.S. has 10.25 deaths per 100,000 people whereas the U.K. has just 2.86—a risk level of 257 percent, which is much higher than risk-per-kilometer.
