I don't drive thru tunnels looking at the ceiling. I just want to get to the end as soon as possible and live to tell about it.......

But you see the ceiling, anyhow, ahead of you, as you drive. Trust me, you wouldn't like looking at the ceiling without some sort of ceiling. I've been in mine tunnels, and lots of other underground excavations. They're not pretty.
You won't find unfinished tunnels anywhere lay people go on a regular basis. It's just too scary.
