The Autobahns, these impeccable highways with no speed limit, often used as examples when it comes to mobility, are at risk.
A German government committee is studying the issue of setting a speed limit, not for safety reasons, but for environmental reasons.
The absence of a speed limit, with engines running at full speed, would produce more harmful emissions than a proposed limit of 130 km/h or 80 mph.
This recommendation has been issued by associations and environmentalists.
The proposal is being discussed as part of new laws aimed at reducing greenhouse gas emissions in various sectors of the economy, reported the Bild Zeitung newspapers, and the Frankfurter Allgemeine Zeitung.
The proposal was badly received in Germany, some columnists judging that there were already enough speed limits in the country.
According to Chancellor Angela Merkel, the government has no choice to significantly reduce CO2 emissions from motor vehicles by 2030 due to the signing of the Climate Agreement signed in Paris.
The committee is also recommending an increase in taxes on gasoline and diesel by 59 cents (US) per liter by 2030.
