My car has 205k miles, and the speedo cable hasn't been replaced...it bounces slightly at certain speeds, but it's not a big deal.
Like
Jet stated, lube it before it breaks. 99% chance that this will cure the bouncing. One thing to note though as I have had this happen to me is that the bouncing was actually from the speedo head unit itself causing the problem. There is a tension/calibration spring and a rotating magnet that are used to operate and calibrate the unit. One of those two items was the reason that mine was bouncing. Bouncing stated, so I lubed the cable, still there, so I changed the cable, still there, changed the head unit and problem was no longer there. reinstalled the original cable for shits and giggles and still worked flawlessly. Again, as I stated in the begining, 99% of the time it is the cable.
Jet, good point about putting it in backward, but IIRC, they cant be. Either way, still a good point and thing to know cause some can be and I speek from experiance that yes the can unwind themselves in the lining. Made that mistake once, dont think that I will do that again.
As for the topic of this thread, Yeah I guess that you could do it otherway, Like through GPS, or possibly using a signal from a ABS sensor if the car is equiped with ABS. Easiest though would be to change the cable and keep the car funtioning properly
