Elon Musk's latest sci-fi dream a 'slick publicity stunt'

Key points

• Tesla has unveiled its redesigned Roadster, which Elon Musk says can fly like a rocket, roll and perform mid-air acrobatics. Production is not due to ramp up until 2028.
• Experts say the car is unlikely to drive on Australian roads. Michael Milford of QUT called the unveiling a slick publicity stunt, saying flying cars are still far from safe use.
• Milad Haghani of the University of Melbourne said it appears to be a technology showcase with no clear path to wider use.
