Sure. That one aspect raises another energy requirement of non ground vehicles.
Land vehicles can stop without expending energy. Air vehicles require extra energy to stop or turn.
So apart from a very great amount of energy to levitate, even more energy is needed to stop and to turn.
Historically, this energy requirement has hampered every previous attempt at flying (even our aeroplanes).
Has Mr musk found a new great lightweight energy source?
If not, the magical levitating car is just a PR exercise, probably aimed at raising money.
