That must be a very big car to have enough space for 4 billion people to write whatever they want on it.

They don’t. I censor them

They can write small.

Also, since you seem to be new I'll let you know. This isn't bad faith. It's reductio ad absurdum.

No. They’re both private property.

So were people.

I thought we were talking about government compelled speech.
