Alcohol

  • 70 people per year are killed in alcohol-related traffic accidents. That is 20% of the total number of killed.
  • 15,000–20,000 drunk drivers per day.
  • 30,000 people are caught drunk driving each year. 10,000 of these are due to drugs.
  • 50% of all drivers killed in fatal single-vehicle accidents were under the influence of alcohol.
  • 30% of cyclists and pedestrians killed were under the influence of alcohol.
  • 90% of the drunk drivers are men, primarily younger and middle-aged.
  • Young drivers are overrepresented in these statistics. They drive drunk more often and run a greater risk of being killed.

Example

How much spirits (40%) corresponds to 50 cl of light beer with 3.5 percentage alcohol by volume?

Answer: 3.5 * 50 * 0.025 = 4.38 ≈ 4 cl

Children safety

  1.  Height > 350 cm = can use normal seat belt
  2. Height < 350 cm = have to use safety devices such as baby car sit
  3. short distance && ( age > 3 year) && (Height < 350 cm) = can use normal sit belt
  4. short distance && ( age < 3 year) && (Height < 350 cm) = can use behind baby sit provided by taxi

Pollutions

Hydrocarbons (HC)

  • Causes cancer.
  • May impact on genetic material.
  • Contributes to the formation of tropospheric ozone.

Nitric oxide (NOx)

  • Contributes to the acidification of soil and eutrophication of lakes.
  • Impacts on human genetic material and airways.
  • Contributes to the formation of tropospheric ozone.

Tropospheric ozone

  • Ozone that forms too close to the ground is harmful to plants and animals.

Calculate kmh to mh = remove 0 then multiply by 3. For example 70kmh. So per 1 second it goes (7*3) = about 21 / 20 m.

Wild animal 

Bears, wolves, wolverines, lynxes, elk, red deer, fallow deer, roe deer, otters, boars, mouflons and eagles must be reported to the police, even if you do not think the animal is injured.
