Considering how many deaths there have been at Le Mans (closest comparable organised race I can think of), this is certainly irresponsible. I wonder if they went through a jurisdiction where the minute by minute trace from the tracking company would be enough to prove they broke the law.
* Everyone on the track is doing a race. No mother with a crying child on the back seat having a momentary lack of attention, getting in your way.
* Everybody is roughly on the same speed scale. No slow lorry around the corner or behind the slope, doing a third or a quarter of your speed.
* No bikes or pedestrians.
* The track is known to be free of obstacles. If an accident occurs or any obstacle ends up on the track, people with huge flags jump out and signal danger.
* The track is surrounded by safety zones designed to stop you moderately gently, especially in danger spots. So if you loose control, there's first green, then stone-beds, then hay and last a hard barrier. This allows even motorcyclists on the track to have a significant chance of survival. It's not the fall that kills you, it's the high speed impact on an immobile object.
So when you race, be responsible to you and others. Stay on the track.
They clearly did not initiate violence against anyone, therefore, any intervention limiting their freedom to recklessly drive at insane speeds for nearly 29 hours with basically no sleep would be immoral.

[EDIT] To all the people who are downvoting; I am pointing out that I agree that it was a stupid thing to do but just saying "go on a race track" is pointless because he wanted to do something that cannot be done on a race-track. It is like telling someone to go to a climbing gym instead when they really want to conquer Everest.
However your suggestion will not help because he was not after the experience of a race track, he was after the experience of breaking the record of the canonball run.
From an aesthetic point of view I really like the cannonball. From a practical point of view I suppose doing it does make you a bit asocial.
I can relate. It's the kind of stuff that movies are made of. But one important property of being a responsible adult is that we're able to distinguish between fact and fiction and keep everything that's fiction safely on that side. So let's keep cannonball and all those other races on public roads where they belong: in the movies. If you really think a race across the states on public streets is great I guess you can get those roads blocked by the police - which would be totally fine with me. I really enjoy watching the Tourist Trophy.
Unless there's a police car visible, when everyone drops to 68 and there's a huge tailback.
Or they're on the M25.
But you do have a good point--this doesn't account for all of the difference.
Recently, I drove from NYC all the way down to Miami. Speed limits make sense on the Blue Ridge Parkway, because of all the wildlife. But we were also passing endless roads that went just straight, perfect view, perfectly wide. This would be a typical spot in Germany where there's simply no speed limit, because it doesn't make any sense.
I noticed something else in the States: People on Interstates and highways stick relatively close to speed limits. However, once you get into city limits of bigger cities, everyone seems to drive at least 10mph over limit, if not more. In Miami, there was a point where not a single car(!) was driving the maximum allowed speed, but at least 10mph faster. But I noticed a similar thing in other major cities as well.
I never understood that.
In Chicago, 10 over would be slow. On the tollway that skirts Chicago, the limit is 55, but 80 is not uncommon.
I think the speedup is kind of a natural thing. When commuting, everyone on the road knows the road and conditions very well and are all in a hurry to get to the office or home. And from a practical standpoint, this speed tends to maximize the overall flow of traffic. And the thinking is that you stand out on the road in the rural area, but in the city, you are one of zillions.
To say "pretty much everyone" is false.
