Just curious: Was there a demo of a stable straight jump as well, or always barrel-rolls?
It must be incredibly difficult to keep the car stable while mid-air at low speeds, I suspect it wouldn't look that "elegant"...
Wasn’t stable. The straight jump they did was more like a mini rocket launch over some parked cars.
You’d want something that smoothly hovers rather than a launch then catch with boosters.
the jump over the cars I saw also had a barrel-roll as soon as the thrust of lifting off was over.
Was there a second jump without a roll?
99% times when you go to write 'barrel roll', just write 'roll'.
A barrell roll is a specific manoeuvre involving pitching up vertically before commencing the roll.

In the kickflip video it launches straight up and then proceeds to do a flip mid jump. The straight takeoff looks pretty solid to me.
On takeoff you can stabilize against opposing forces, so especially without the weight or inertia of a driver it is quite straight (rockets also don't need to stabilize on take-off).
But once that phase is overcome, how stable is the car actually mid-air?
It looks to me that they added the barrel-roll because everything else would have looked worse...
