Flying is actually much more dangerous than driving. The risk is to destroy the environment that sustains life on earth. This does not even compare with the risk of a car or plane accident.

I believe it might be better for the environnement to share a full plane than be alone in your car, for equal distances.

  Quotation needed. All studies show the impact of flying as being much higher than driving, even when shared.

      I think you are comparing unrelated things. The average car ride is thousands of times shorter than the average flight, and transports more than one person. You cannot just compare the average emissions of cars and planes and make the conclusion that it makes sense to choose a plane over a car to reduce your carbon footprint. And even when you make this comparison with sensible data, the car still wins: https://ourworldindata.org/travel-carbon-footprint https://ourworldindata.org/travel-carbon-footprint

        when comparing driving to flying between destinations, it's highly likely that the flight will have a shorter duration. The big wrinkle in this comparison is that planes burn most of their energy in the ascent to cruising speed/altitude. Energy consumption per mile is likely to be much higher on a short hop flight where cruising altitude is never reached than a 12 hour transoceanic flight.

        On the other hand short-haul flights don't climb to as high of altitudes. They only climb about 2/3rds as high. But then again the air is thicker so cruising is less efficient. Oh gosh, for want of data.

        You have to assume that airlines have chosen a decent compromise here. Every wasted joule of energy translates to a higher fuel cost and a lower profit margin.

      If also air distance calculated as the crow flies vs actual car km the numbers will be more air travel favirable

If you are alone in your car, flying and driving are in the same ballpark when it comes to emissions. Trains are much, much lower. Especially considering that in France, most lines are electrified and 70% of production is nuclear.
