[5] Road toll figures in developed nations show that car collision fatalities have declined since 1980.

[6] Besides improving general road conditions like lighting and separated walkways, Japan has been installing intelligent transportation system technology such as stalled-car monitors to avoid crashes.

[16] Source IRTAD for the following data: The 28 EU-28 countries, for the 28 members, computed an indicator named "per 10 billion pkm".

[19] The safest of those 28 nations was Sweden (22 deaths/million inhabitants) while Romania reported the highest fatality rates of the EU in 2019.

According to Eurostat the automobile is one of the least safe means of transport, if safety is measured as the fewest fatalities per travelled distance. Based on data by EU-27 member nations, 2008–2010. [ 11 ] [ 12 ]
