Smoky Dragon Dish: Kibbler: It would make the people who drive at 80 go 90 instead.

I sometimes drive at 70.  In daylight, with dry roads, perfect visibility, and light traffic.  Otherwise 55.  Because I understand the (enormous) difference between a crash at 55 and a crash at 70.

Took me a minute . . . but I got it.

/Of course, they'd be riding in unbreakable cars with a a stasis field that would cut in at the time of impact.

You have once again executed an unsafe maneuver, Yeeeeeehaaaa does not compute..:

This text is now purple: draypresct: (vehicles are crash-test rated only up to a change in velocity of 30 MPH

That's 60 mph, if you hit a stopped vehicle.

/It's 30mph if you hit a tree, or another car also coming at you at 30mph


You're right about the crash test being for a delta V of 30 (or 35 - I forget) MPH. Thanks for pointing that out.

I'll try to weasel my way out of my mistake with a few points, of decreasing validity:
1) The collision is not completely inelastic, so a collision with a stopped vehicle at 60 MPH results in a delta V of in the striking car of > 30 MPH, even if both vehicles weigh the same. In a 2-minute search on Google, I haven't found any hard data on the elasticity of the collision, though.

2) I think that many crashes are immediately preceded by some attempt at an evasion maneuver. The only evidence I have to support this is offhand reports of the number of deer-related fatal accidents in my home state. These are not deaths due to a vehicle colliding with a deer. These are deaths related to losing control while trying to avoid collision with a deer and hitting something unmoving off the road (in some cases the "something unmoving" is the ground after a rollover).

3) Much, much less of an issue: the stopped car probably has other cars ahead of it, so instead of a single 30 MPH delta V, you have a 30+ MPH delta V followed by another crash or two.

K.i.t.t never told Michael Knight that he was being too dangerous when he was turbo-boosting all over the place every week. Saw an old episode recently with my son (I'm trying to show him the way) and I realized that there's ALWAYS a flatbed truck or a row of cars in Michaels path when he's trying to apprehend someone. *TurboBoost*. It reminded me of a Simpsons episode about Night Boat - The Crime solving boat.

Here's the thing. You have to be conscious of the fact that force equals mass times acceleration.

This translates as: If you're doing 45 to 55MPH and smack into something you'll probably walk away from it. If you're doing 75 and up your organs leap out of your body in a heavy deceleration phase. You usually don't survive that.

It's a nice idea, but there are more useful implementations. For example:

"Your present speed is unsafe, but that is irrelevant to the fact that your death is inevitable."

"If you died while driving this fast, you would do so having never really lived."

"Your speed is 150% of the maximum safe speed for these conditions. Engaging computer override. Reducing speed. Connecting to internet... connected. Establishing connection with home computer. Deleting browser history and contents of designated pornography folder. Returning control of vehicle to driver. You may resume your unsafe speed."

In japan they already have a colored triangle affixed to the bumpers of 1st year drivers and the elderly.

Such a good idea.

You know who else liked affixing colored triangles to purportedly dangerous people?

People will just drive faster to see who can get the most severe message.

It's the same reason that they don't show BAC numbers on breathalyzers in bars. If you give them a number, they go for the high score.

I thought they were well out of Known Space by now.

Considering all of the Russian crash videos that circulate on Fark, Live Leak, Epic Fail,
perhaps they should test run this in Russia and see if it works LOL.

Great Idea! Let's distract the unsafe drivers while they are travelling at dangerous speeds. I'm sure this will work out well. Hell, lets just project the warning on the front window and completely obscure their view of the road.

ZAZ: Claim 6 of the patent explains who the real market is: fleet owners. That claim says the device can phone home to tattle on drivers. Some lawyer out there thinks this was not obvious as of the 2010 filing date.

The severity of the collision is calculated based on vehicle mass. If you're driving a semi and approaching a motorcycle, you're going to die because you have 40 tons behind you. If you're driving a motorcycle and approaching a semi, no big deal because your vehicle weighs a tenth as much as a car. Not much kinetic energy there.

I don't see anything in there to account for other vehicle speed. The assumption seems to be that the vehicle ahead will instantly slow to zero speed. Since braking distance to a stop is greater than normal following distance this device will constantly alert whenever you are in traffic.  But as I said you aren't buying it for yourself. The fleet owner is buying it because a salesman said it would help track unsafe driving.


I'm guessing it will all be up to the insurance companies.

Yay.

Couple of days ago, my navigator/reminder of misdeeds (the Baroness) came over the console and into my lap when she made the mistake of looking down. We were on a snow covered single lane track in the mountains, with a several hundred foot drop about a full 12 inches off my right wheels. I nearly went over the edge just from the shock of her freakin' out.

Came here to... uh... somethingorother this. Gotta remove the seatbelts, too.

Way I figure it, the number of crashes the day after these became mandatory would be about the same. The day after? None.

FTFA: "You would die if you crashed right now." Would such a warning make you take your foot off the accelerator?

I know many people who wold consider it a badge of honore to see how many times they could get their car to say that on a trip. It would be an incentive to speed and drive wreckless for some.
