The same benefit, it would save on budget.
The most obvious benefit would being able to park in no-parking areas. I could also see some advantages when Batman has to pick up somebody at the airport. It would also get him out of a lot of tickets for speeding and running traffic lights.
True, and so obvious I did not think worth mentioning.
Not true. My point stands that it is possible to fly a plane without seeing the instruments.
So for about…12 hours, during the summer, depending on latitude? Depending on speed and direction of travel. If Wonder Woman gets to wear night vision goggles, that’d help.
Yeah, 12 hours out of the year. I’m sure that’s about right.
I meant “per day”—but depending on maintenance requirements from scraping birds out of the invisible canopy and engines, 12 hours of useful flying time per year might not be THAT far off. 
:smack:
Sometimes I get a little defensive – but only when discussing really important stuff, you understand.
Valet parking would be a bitch too. 
I kinda like the idea of visible fluids in an invisible car or plane. You see not only Batman, but a large volume of gas, and a 3-D network of fluids all around him. Brake fluid, hydraulics in the shock absorbers, oil everywhere… You would even see all the cylinder explosions. Kind of hard to be stealthy when you have several thousand small flashes every minute.
Does an invisible Batmobile need windshield washer fluid?
Yes but if you see anormal nondescript car driven by a man dressed as a giant bat its still a bit of a giveaway.
He dresses that way because he’s a coward, “Hey look bad guys I’m sneaking up on you , look at me bads guys”
“Oh look they’ve buggered off!”
