To be fair that’s probably by design. The demo roadster uses McMurty fan style or “active downforce”. How it works is that it sucks the air out from under the car creating a low pressure chamber under the car which makes the outside pressure force the car closer to the ground creating a lot of downforce and traction.
The fan design also made an appearance in F1 where it won a race and got instantly banned.
You can see the underside of the vehicle during the demo. It’s hollow with a metal lattice.
