seeing as people are willing to spend $84.6m on a 1981 Francis Bacon painting, surely somebody would be willing pay to have kudo of their name alongside 'the 1st car to break 1,000 mph' in history books, even if they're not the driver.
My uni named the business school after the man who donated 5 milllion GBP*
But then reality struck. people who have the money and the interest are (were) already doing these kind of things - Elon Musk, Jeff Bezos, Paul Allen, et al. Others pile money into medical philanthropy - Bill Gates, Warren Buffet, et al.
People who are happy to buy art for their private collection so that they're the only people who can view it, will continue to do so. Plus, as impressive as land speed records are, they're pretty much an dead end. 1,000 mph is an arbitrary number, why not 2,000 km/h? It's only 24% faster. Don't get me wrong, I still hope to see it happen though.
* So the school had enough spare budget to put on wine & cheese events for students. Meanwhile the engineering department didn't have enough money to maintain a water tunnel. Not that I'm bitter!
