The car will she as quickly as we think?

I bounce on the mail Surun Pierre appeared in the West of France on Saturday (April 9 2005).

I asked myself about the average real speed of a motorist who according to Pierre Surun puts 500 euros per month in his car.
While on the highway maximum speed limit of 130 km / h, it usually happens not to exceed 100 km / h average speed on these long stages of asphalt. It takes the stops to rest and often does not hesitate when these long stages. To ensure that the average highway speed does not exceed the 100 km / h, just observe that the trucks twice twice on long journeys and have enjoyed our stop to take the lead . On long trips on and local roads, the average drops to 60 km / h respecting speed limits. With daily trips, more urban journeys, we see that the overall average motorist is only 40 km / h. Either the respectable speed of a car without a license or still twice the speed of a right bicycle: 20 km / h!
But to this must be added the "lost time to earn money" to pay the right to drive. Based on Pierre Surun's 500 euros per month, which represents the total cost of a car, I counted that, on average, French people work 650 hours / year to pay for the purchase of the vehicle, maintenance, insurance and also taxes to maintain the roads.
With my 40 km / h average speed and knowing that the French travel on average 14000 km per year (less for gasoline and more for diesel), I deduce that the French roll 350 hours per year (roughly speaking 1 hour by day, which gives a good order of magnitude).
By combining the time spent working to pay the duty in automobile travel and the time actually spent in her car to get around, we see that the average speed drops to 14 km / h (14000 km / h 350 650 + h ).
Add to this the social and economic costs of pollution and the actual average speed drops to 8 or 6 km / h.
And I come to the simple conclusion that at this rate, would it not be preferable that we use what nature has given us, namely our legs!
And I open this debate on the potential value recumbents. These bikes are up to 30% more efficient than upright bikes, and one can almost easily reach average speeds of about 25 30 to km / h. Knowing the actual speed of a car, it is worth it to look into the possibility of replacing his car by an efficient bike.
