Perhaps you'd like to get some actual numbers behind your claims?

And not stuff like "trains are very rarely entire full". Of course they're not. But cars are almost always entirely empty.

Hey, I'm trying to throw some actual numbers into the discussion in response to the assertion that trains are more efficient. Perhaps those who want to make that claim can start supporting their own? Give me something to work with here.

Rolling resistance is the big issue that usually favours trains. On the other hand, could we design cars with an extra set of wheels or something?

Two vehicles capable of 300kph: TGV: 500 seats 8800kW BMW M5 5 seats 440kW

For long distance/high speed aerodynamics is more important than weight.

Then let's buy 68 million airplane tickets for everyone who will ride this train. The cost will be the same.
