Had never seen the Morgan 3. I looked at your link. It has a single rear wheel and the weight distribution is forward. It is possible that it might actually skid without turning over.
The 3D printed car has a single front wheel and I would never ride in one. Not safe.
They did a segment on Top Gear UK about the Morgan 3. Looked incredibly fun to drive, and never came close to tipping over.
Watch it here:
