How might we help citizens to use their cars less in city centers?
Cars are a major polluter, accounting for 60.7% of total CO2 emissions from road transport in Europe (75% in US).
2020-05-16
Cars are the most popular way of passenger transportation across the EU: they represent around 72% of the total passenger kilometers. However, personal vehicles are rarely energy-efficient as according to data from the UK, 60% of cars have only one occupant. Transport is responsible for roughly 25% of the EU’s greenhouse gas emissions. Road transport accounts for 71.3% of this amount (2008). A regular rush-hour driver wastes an average of 375 litres of gasoline a year due to traffic. The average cost of the time lost in rush hour traffic is $1160 per person. US Public transportation saves more than 3.2 billion litres of gasoline annually, a level equivalent to the energy used by 25% of all American homes energy consumption a year. One bus could carry the same number of people as 30 cars, while only occupying the road space of three cars. If one in 10 Americans regularly used public transportation, U.S. reliance on foreign oil could decline by more than 40%. Passenger traffic is projected to increase by around 50% by 2050 compared to 2005! Traffic jams result in 5.7 billion person-hours of delay annually in the United States. Electric vehicles growing market impacts are to question.

Comparing Thermic and Electric vehicle reinforces the automotive paradigm and contains many cognitive biases
Let's challenge the comparison with other means of transportation and also ask questions about the way we use energy?
2020-06-19
In the bellow infographics we are told that electric cars, for a 150 000 km range, emit twice less CO2 than Thermic ones. We will consider that the measurement system is reliable even if we do not have any evidence that the retained parameters are exhaustive. The metric itself has a major bias. It doesn't tell anything regarding the number of passenger in the car neither on its load. Then, we are comparing a car with an other car and we do not have any other comparisons for instance with a bus or a bicycle... It doesn't tell anaything about the infrastructures and equipments needed to produce the vehicles neither about those needed to recharge them. The same source, ADEME, publishes the comparison for several means of transportation. For 1 passenger doing 500 km, the CO2 emissions represent 170 kg for a thermic car and an average of 190 kg for a plane while it is less than 60 kg for a bus and 12 kg for a standard train and almost 0 for a bike. So, even if you were using an electric car you will only reach the train efficiency if you put 6 other persons in the car with you! This to demonstrate that we need to be careful with data and that new paradigms have to be found...
Between Thermic and Electric, which vehicle emits the most CO2?

Bad problem statement may lead to poor solutions
Scoping a challenge is an important step to focus on
2020-05-21
I chose voluntarily a vast subject. It is not a big deal at the very beginning to try to embrasse the big picture. But, the fact is that it might be very difficult, or even impossible, to find a unique solution to a too large problem as soon as it might be more a problematic regarding its complexity and various analysis angles it needs to be understood and addressed. It is why this quote makes sense: "A problem without solution is a badly posed problem" - Albert Einstein. This challenge is in the problematic area. There are so many reasons why you may use your car in city centers that my entire life will not be sufficient to listen to them. So What? The first step for that challenge will be to collect data to try to subdivise the problematic in problems that might be more simple to address. It is where you are very important. We are going to define a methodology to collect data in a way it would be easy to understand the phenomenons. Then you will be asked to contribute to the measurement system on a volunteer basis. All the process will be public and tranparency will lead us to objectivity. If you want to contribute to the Measurement System Design text me.
