Ford Exec: 'We Know Everyone Who Breaks The Law' Thanks To Our GPS In Your Car

[2011GT]

Okay, explain to us how cell phone signal triangulation can determine exact speed. It isn't as accurate as you think, and varies greatly from depending on provider, tower available and terrain.

Hell half the time I'm lucky to be picking up one tower

[Snatch Napkin]

That snapshot junk that Progressive uses does the same thing.

I had to put it on my truck for a while in order to get my driving style logged. It gives out a beep to let you know when you've done something they aren't fond of. I'm not sure who programmed this bitch, but it has considered my braking to be too hard on 3 occasions. Neither of these occasions were hard enough to shift things in the bed of the truck.

It's as accurate as GPS in most instances. Down to +/- .1 mph.

That is odd, from what I read the lowest average accuracy is 40 meters, the normal average is around 100 meters and that an inaccuracy of 1200+ meters is regular seen in rural areas. I cannot see an error margin of .1 mph with that much inaccuracy.

The MPH is based on the rate of change, it could be off by 10 miles and still see that you are moving at 65mph. A broken scale may not give you your correct weight, but you can still use it to calculate how much you've gained or lost since the last time you were on it.

[Strychnine]

MPH... rate of change

Acceleration.

[Big A]

Acceleration.

I meant the change spatially. It may have your location wrong by 10 miles to the south, but if in the next minute your "dot" has moved a mile to the east, it can accurately be determined that you're travelling at 60mph, regardless of the 10 mile shift south.

Acceleration.

Strategery.

That looks to be 12-14 year old accuracy.

[orphan Shelby]

And that is why GM is better.

Actually with Onstar they can listen inside the vehicles.

[94form2000z]

Hell I cannot think of a day in my life since I've got my license that the law has not been broken. Oh well. Log that shit all you want Ford.

[Nash B.]

Acceleration.

technically, you're both correct. v = ds/dt, a = dv/dt = d2s/dt2

[slow99]

technically, you're both correct. v = ds/dt, a = dv/dt = d2s/dt2

Look at me - I'm the fancy physics guy.

[Nash B.]

I put off college science until the summer before graduation so I had to take the non-calculus physics course. It's just not the same without integrals and derivatives
