Is the new logo acceptable trade dress?

Hello! New driver here. Is the new Uber logo (the backward C... or toilet seat... or whatever it's supposed to be... an atom??!!) acceptable as trade dress? The temporary downloadable version is the old U logo. I'm making laminated ones with suction cups so I can remove them when I'm not driving. (My state requires 2, and I don't mind complying). I'd rather not waste materials making U's if the new logo is also acceptable. Thanks!
