You fly as Iron Man. Soundbarier breaking rocket jets with great thrust boost from your hand and feet. From the rooftops a webslinger joins you with his fast acrobatics and specialised webbing. On your right from the crossroad rides Logan on a borrowed ride that hums with power. He drives next to you. Then a supersoldier with his superspeed comes "on your left" and matches your speed. And finally dressed in tight dress and wearing high heels there comes Emma Frost running fast like a super-soldier, speeding as a bike and performing like high tech rocketpowered flying suit.
I understand that balance is needed and when you play that hero it's nice for you to travel as fast as others to enjoy the game and make it in similiar time. It just a funny sceen I see since Emma got her running [before a lot other characters did].
