That overblamed decision was (a) specific to Michigan corporate law, and a reason why Ford reincorporated in Delaware shortly afterwards and (b) a finding that Ford had to pay dividends to its shareholders rather than reinvesting profits in expansion, which no modern court would require. Warren Buffett and Steve Jobs both cancelled dividends and nobody objected.
The story behind the lawsuit was that the Dodge brothers had just left Ford (then a private company) and they planned to use their dividends to start a competitor - which Ford suspected and which is the reason why the dividend was canceled.
I don't doubt that it's possible to find out what kind of car the jury members drove, but is there actually a public record of it? If so, please show the link.
