Guillotine Anti-Slide Spinners

When you need to stop RIGHT NOW

These are specialized spinners.... well, half-spinners. Well, not quite. Rather than spin freely, they stay still while the tire spins. They look like a spinner with the bottom half removed. Basically, they look like guillotines, complete with razor-sharp blades on the bottom edge.

In the event that the vehicle begins sliding or skidding, a warning light comes on (this is for the novice drivers who claim they can't tell when they lose traction). Simply flip the red guarded switch that is located on the steering wheel, and the guillotines slam down, cutting through ice and standing water, and possibly a milimeter of asphalt. Even if the blades don't cut through, they're going to add a lot of friction in a very short amount of time, bringing your vehicle to a much quicker stop than normal braking would allow.

       [+] But how thick would they be? A blade a few millimeters thick would probably grind down sooner than a thicker one.

       I was thinking about a quarter-inch thick.

       wouldnt this throw off tires balance? a quarter inch piece of steel on lony half the tire at about 50 mph is one hell of a vibrator.
  

       maybe mout it on the frame instead so you dont have to deal with rotational forces.
  

       i do like the idea of razor sharp guillotines spinning at high pm and potentially flyinf off and decapitating someone in an accident though..

       You're missing the point. The guillotine doesn't spin. Nor would it cause any vibrational problems because it stays oriented in the same position constantly.

       I love the way that you suggest that something similar to an ice skate would be good for stopping on ice.
  

       I suggest a set of bolt guns that are linked to a cable, that ought to stop ya with a large degree of whiplash

       I tried that idea, and it was already baked on this site so I deleted it, even though there were a few noteable differences. There were a lot of objections to that idea, I'll see if I can find a link for you.

       [marklar] I suppose that 21_Quest was thinking that the car would be sliding sideways... And I doubt that the semicircle as described would be as much like an ice skate as you seem to think... The bottom of the Un-Spinners wouldn't be curved up in the front... In fact, an improvement might be to have the bottom be a series of triangular points like crampons that would dig in like crazy.

       That makes sense that it would stay in the same place... I believe the logo in the Rolls Royce Phantom has some mechanism that allows it to not roatate. Neat. Seems like the worst possible scenario is that the thing comes off and lands on the ground.

       this would be good hear in Canada but the government will not let use steal chains in are car's so this will probably get band to.

       The opposite of spinners are called floaters.

       Ah... thanks.
21 Quest, Nov 29 2006
  

       Quest I think this has been recomended before...SLOW DOWN.

       Even driving slowly, hydroplaning and loss of traction can occur, Chef. I slid into a curb going 15 mph because I was on solid ice and couldn't stop. I slid about 30 ft, and I have all-season tires equipped. It happens, and it happens regardless of how good a driver you may be. This is for when it does.
  

       My point? Simply driving slowly isn't as perfect an answer to every problem as you seem to think it is.
