Wow, we got the flying car! It’s always impressive to see how Elon & team executes projects with sheer determination. It is clear that flying version of the roadster will likely never get past the demo vehicle (aka vaporware) phase. But, the fact that they made the concept car work is a phenomenal engineering success story.

Coolest part: the actuators that control the 10,000 PSI nitrogen cold-gas thrusters are from the Optimus robot project, which I found really surprising! It just shows how much technology development had to happen before we could get to this place.

Biggest question: how long do the tires last? With that much downforce and torque, this car looks to be a rubber shredder.
