1 minute might seem like a lot when you're walking or driving, but when coming in at 200mph in something that weights hundreds of tons ... I want that guy 1 minute ahead of me off the runway ;)

And that's considering that existing traffic is of similar speed and ability. Adding slow, small, low-performance aircraft to the mix makes things very interesting ;( Then add low-experience pilots who have to stop and think about procedures, actions, radio calls ...

permission to back their car out of their driveway - It might be different if those cars cost $100M-$300M. A tiny bingle is very expensive.
