Every year thousands of people are killed in traffic, often under the influence of alcohol or other drugs, either by crashing into something, or by being crashed into. Special safety features have been built into cars for years (some for the safety of the people in the car only, some for the safety on the road in general):
There are standard tests for safety in news automobiles, like the EuroNCAP[?].
With heavy taxes on fuel, particularly in Europe, tightening environmental laws in the United States, particularly in California, and the possibility of further restrictions on greenhouse gas emissions, work on alternative power systems for vehicles continues.
Nowadays petroleum cars can use 100% pure biodiesel, a fuel made from vegetable oils.
Attempts at building viable battery-powered electric vehicles continued throughout the 1990s (notably General Motors with the EV1[?]), but cost, speed and inferior driving range made them unviable.
Current research and development is centred on "hybrid" vehicles that use both electric and combustion (pollution) power, and longer-term efforts are based around electric vehicles powered by fuel cells.
Other alternatives being explored involve methane and hydrogen-burning vehicles, and even the stored energy of compressed air (see Air Engine).

The question as to whether it

Aeroplanes have been constructed with floats in the place
cases successfully, to light with them on and to rise from the
1911. Attempts have also been made with the aeroplane to
the end of 1910 Aviator Ely flew to land from the
and alighted on the cruiser Pennsylvania. But in these cases
in a time of actual war.
