Even with modern efficiencies available, I doubt they'd do more than double that, so a car would still easily win, unless the car had one person in it and the plane 4.
So more like 3 times better performance is available with a modern design... Kind of makes you wonder...
But air miles and car miles are not equal. The car route is nearly always longer, even in flat terrain roads don't usually go in a straight line to the destination. Adding in mountains or water makes that worse for the car.
For example driving Amsterdam to Barcelona is 1554km according to Google Maps. The flightplan route is 1236km and usually the really flown route is a bit shorter if ATC allows. That's 20% less miles for the airplane.
The most extreme ones fly without an engine at all (gliders).
Great choice of words to calm the passengers as we lose all our air worthiness.
Negligible lift. Fluid flowing around an object generates lift. Drag is more intuitive; if there is drag, there is lift. (They're just components of the aerodynamic force relative to the direction of relative fluid flow.)
