"Now, after waiting some 10 years, Gates can finally enjoy his other favorite Porsche: a rare (1 of 230) 1988 Porsche 959 Coupe. In fact, due to the 959’s questionable emissions and unknown crash ratings, it took a federal law signed by President Clinton for Bill Gates to legally drive his 959 on American roads. Rumor has it that Bill Gates and Paul Allen employed Microsoft engineers to write a computer program that could simulate the 959’s crashworthiness, which helped in the bill’s passage."
