According to Jon Callas, CTO of Entrust, and someone who has done senior security roles for Apple before, Steve Jobs found a loophole of sorts in California license plate laws. If you had a new car, you could drive plateless for 6 months (of course, you still had to register). So Jobs, being rich beyond belief, decided he would just lease a new car every 6 months. He came to terms with a leasing company and switched out his 'old' Mercedes SL55 AMG for a 'new' Mercedes SL55 AMG twice a year.
It's a hilariously logical rich man way of thinking to side step the law. Or a crazily convoluted way to stay different. [iTWire via Jalopnik]
