Some of the trucks will still run right into it. Raising 8" to 12'4" will still see a lot of vehicles getting opened like a can. With the Average Semi Being 13'6" high I don't think the can opener bridge is going away anytime soon.
If I remember part of the Viel Nebula is called the Witch and Broom nebula as well. You have to look at it just right but you can see a witch and her broom in the nebula.
I agree with you some of the sites just feel like filler. It also is a very "eye of the beholder" list. I don't think it has very clear details on what makes a site "important" vs. any other site.
If we can make it self driving then it might have a place in the market but I hate the idea of everyones cars flying around with everyone driving them. It takes a lot of work to be a pilot and I don't see people being very safe about these things. Also we'd have to change our electrical systems to allow clear landing areas. In the end it would probably be like short hope airports instead of just take off/land from wherever. Anyway Flying cars are still a long way away.
