Elon Musk 2.0? Meet Austin Russell, the world’s youngest self-made billionaire, Luminar founder and evangelist for the lidar self-driving car tech that Tesla’s CEO called ‘freaking stupid’

• Elon Musk calls lidar ‘expensive and unnecessary’ but 26-year-old Russell, on Forbes’ ‘40 Under 40’ list, believes otherwise – and has deals with Volvo, Toyota and Intel to prove it
• He left Stanford after getting a US$100,000 fellowship from PayPal co-founder Peter Thiel and now owns an US$83 million LA mansion next door to Tom Hanks and one in Florida
