I don't think it is as fast as you say. It is some where between 650-750km/hr. The image that this blog shows explains how that might look and work http://www.techcrump.com/travelling-the-world-in-6-hours-elo... but the fact that it is anti-crash is totally unimaginable if the traffic increases it is likely that the crashes would be reported, lets see what they put together i eagerly waiting for it to launch.Just a little too exited
Where do you get that figure from? The speed of sound is around 1000km/h,right? Still one hell of a stop but it might not be that fast, since basically its the air drag doing the braking.
Yeah, where did you get those numbers? The distance from SF to LA is about 380 miles, and the speed of sound is about 760 mph. Whether or not the principles of sound movement are involved in Musk's plan, the speed is roughly equivalent if we're talking traveling back and forth in half an hour. Still a jolt, but you're talking about six times that.
>Safety is no small concern when you're talking about speeds in excess of 4,000 mph (6,437 km/h). After all, we've all seen the wreckage that can be caused in a 60 mph (96 km/h) car crash. The kinds of tube tracks we're talking about here would have to stretch thousands of miles in order to reach their optimum level of benefit – that's thousands of miles of safety risks. What happens when an earthquake strikes and cracks the pressure seal or destroys the tube completely? A vehicle traveling 4,000 mph is going to eat up some serious distance in an emergency stop situation.
Actual stats from Great Britain in 2008 on motorways, presumably always speed limit above 50 MPH, "6% of the total killed, 3% of total seriously injured, 5% of total with slight injuries." at least per wikipedia.
So there's about a 9 in 10 chance if you crash on a GB motorway, at least in 2008, you'll walk away without a scratch, rather than your 1 in 5 stat.
Also all minor aircraft accidents involve flying faster than 50 MPH although death from anything but fire is relatively rare. True though, that controlled flight into terrain at cruise speed doesn't usually leave many large pieces on the mountainside.
You are confusing the speed limit with the speed at which the crash happens. Most people apply breaks before the crash, and do not crash at full speed.
Of course, in a closed system that isn't directly touching humans, it doesn't necessarily have to use those conditions. Still, I don't think you're going to get anywhere near 6400km/h.
