I’d take this in a red second. Even at normal walking speed, the ability to go directly from point A to B without the need for true navigation would be an amazing time saver. Think of what you could do with such an ability! You could buy an old factory type building and use all the walls for things! No stairs to get in the way so long as you can heft the items you need to elevate. Travel in rough country is essentially a snap, and you could go anywhere with relative safety.
There’s a problem with the scenario. If you can only fly as fast as you can run, then you wouldn’t be able to make enough headway into a strong wind to get anywhere, unless you are unaffected by wind, but that means ignoring more and more physics.
Does this ability allow us to jump from a height and recover once we get to within 1000’ from the ground? That might be fun.
The same could be said for an aeroplane pilot, it’s rare enough not to be a big problem though. Probably more chance of having a heart attack.
Reminds me of a late 70’s or early 80’s diagram of Supie’s Fortress of Solitude. (Before the movie’s crystalline crap.) There are “stairways” at opposite sides of an essentially boxlike structure (excluding Supergirl’s extra modular apartment and the tube-like connection). But the “strairways” were essentially vertical corridors that connected the three floors, with no steps, or anything at all to step up on. It was no problem, of course, for Supie or his “kissing-cousin” Kara, who also had full access to the main Fortress. But it kept * most visitors [/I ]from seeing anything on the two higher floors that gave away Clark’s true nature (and perhaps other carefully guarded secrets).
The main floor was fully accessible to any and all guests, since it lacked the slightest clue about Kal-El’s double life. In fact, when we saw the very first (?) internal scene in the 50’s, we saw the precaution of a fake-out “Clark Kent Room” neighboring those for a young Mr. James Bartholomew O., and a certain Miss L.L.!
The main floor was no doubt the easiest to access for trespassers, as well, since the only doorway and the tube access connect directly to it alone. Getting past the security devices in the keyhole would be a challenge for almost anyone except Batman, who did it at least twice. Once past it, most folks wouldn’t make it to the higher floors, unless they could fly, leap, super-stretch, possess climbing tools (like Batman and others) or wall-scaling (crawling?) powers or were as resourceful as Batman.
This system seems to presume that people who were trespassers or untrustworthy guests always lacked flight or a working substitute. But here were other indications that Supie had the foresight for this, and IIRC, there were more security devices later put it to render certain displays and sections invisible when approached without clearance.
Physics? In a *superhero ^ * scenario? 
I am assuming you can land and just sit?
I mean, I would hate to have to hover like a hummingbird in a movie theater to watch a long film, plus there would probably be some fat-assed pigeon dude flapping his arms in front of me and a couple of stupid magpies chirping with their peeps behind me.
