0-60 distance traveled
I don't really have a safe/legal way of trying a 0-60 time, much less seeing how much distance it takes me, so I wondering if anybody knew how far they traveled, and what their time was, before reaching 60mph?

It's going to vary, but it's pretty damn close to 330ft. I know this because used to do many runs with a GTech, and the 330ft time was usually very close the 0-60 mph time in my stock RX8.
Random RX8 question... funny I knew the answer.

How are you calculating it?
What the hell are you using this for?

Simple. Gather data on your velocity over time in a 0-60 run using a DAQ and your favorite data acquisition software (I prefer LabView), plug your data into excel, use a time step of ~0.05 seconds, plot it, fit a line to your data, take the derivative of your line, plug in your final time step, and voila! Total distance traveled. Oh and don't forget to convert all your velocities from miles per hour to feet per second.

No way of saying... it's variable... which is why 0-60 is a crap way of comparing performance. Best I ever did was 5.75 seconds, and that just could have been an anomoly. I broke 6 seconds only a couple of times, but could repeat a 6.2 consistently.

I was "paced" at 60mph within a distance of 1,000feet after the cop took a 3sec time to react and begin moving.
I proved that if that had been the case (i.e. me going 60) I would have reached the stop light (at the 1,000ft mark) and already have slowed down significantly by the time the cruiser reached 60mph.
I had several papers showing my math and explanation for everything, cop didn't have a comeback to anything I said so judge ruled in my favor, no court fees, all 3 tickets removed from my record (careless driving, 60mph pacing, missing registration).

You know, I once prepared the same thing. I got radared in fog once, and got a f'ing monsterous ticket because I was hauling ***. I know, I know, stupid, yadda yadda. It was stupid, and I was young. Anyways, I started doing the math on the dopler shift radar readings and how the water in the fog would affect propagation, and all this **** with micowave blah blah blah... it was back when I was in college taking some physics courses and I minored in math... I went to go fight the ticket with this paper, and sure enough... cop didn't show up, and I got off.
Would have been damn interesting to present it.

Lol thanks
Here's the short version of what I presented, I can't find the longer version I had written, but it's roughly the same stuff, just significant less detail and the longer version I explored all the different things which would have needed to happen in order for the cop to even manage 1 sec of pacing at 60mph. Mind you, any of this is without counting the fact I had a guy going 30mph in front of me.
Enjoy

You're a bad ***. Much respect. If I helped any, makes me proud to be a part of it.

Yea, call me the nerd haha. The speed of light and sound changes (not sure if radar uses light or sound) when the air is full of water which leads to miscalibration of the radar. Nice, I wouldn't have thought of it.

And guns are calibrated for the weather conditions...and to make it worse, water droplets ought to make it slower to get the signal back to the gun, which would show a slower speed than actual; in effect, you're getting a break from the moisture conditions, and the ticket is already lower than what you were actually going... Take that defense in court, and you're gonna' lose if the officer knows anything about his radar gun (they do).

Umm... Neither...

Oh and it would only help if you were heading toward the radar. If you were moving away from the radar and the wave was slower going through the medium it would appear that you were moving faster - red shift, blue shift.

If they don't use light or sound, what do they use? Note things like microwaves and ultraviolet rays are light...just at a wavelength we can't see.
