Legal Help

Cory1970 · 12-20-2011, 03:35 PM

Hello,

I recently got a bogus charge that I am trying to defend.

I need a reliable source for acceleration times and distances for my 2007 335xi. It is important that I show the impossibility of my vehicle accelerating to 42MPH in the short distance the policed claimed.

It is easy to find 0-60 times, but I really need distances calculated.

Any ideas?

Syndicategt · 12-20-2011, 03:42 PM

Well I've seen 335's with 0-6 in 3.2 seconds on a Vbox. That was an e90 335i....not sure about the Xi but I would assume it can do the same since it has more traction.

apc3libras · 12-20-2011, 03:44 PM

Stock 335i 0-45 in 3.3 seconds. XI probably similar.

Thank you, but I am really looking for distance.

I had been driving half way down a very short city block when the police claimed I had accelerated to 42 MPH.

Assuming constant acceleration during the voyage from 0 to 42 MPH, you would have needed to travel approximately 31m if it takes 3.3 seconds to get there.

I think. It's possible my math may be wrong.

That's also assuming you can prove you were at a stop at the beginning of the block. Otherwise the point is moot.

I don't think you're going to get an adequate source for official 0-42 times.

quick search on google found this hopefully this can give you some sort of idea

By using http://www.engineeringtoolbox.com/ca...on-d_1309.html and using acceleration stats from Car and Driver (I know..) which shows 0-45 in 3.3 seconds, you traveled approx. 108.9 ft.

Yup.

That's a very short distance.

username604 · 12-20-2011, 04:13 PM

i don't know how useful this is, good luck OP, even if you get convicted of doing 38mph, if the street limit was 35 you're just as guilty in the eyes of the court.

this by the way isn't accurate because acceleration isn't uniform.

Yup.

Unless the "short city block" was a whole lot shorter than the results posted, I don't think math is going to be able to get you off the hook here.

So...

...were you traveling at 42MPH?

cgpublic · 12-20-2011, 04:38 PM

Q. Is is possible to attain the speed of 42 mph from a dead stop within a single city block when driving a BMW 07 335xi?

A. Yes, your honor.

You: Profuse sweat.

Verdict: Fail.

E90Brad · 12-20-2011, 04:50 PM

Just do what I do. Pay the ticket and every time you see them on the side of the road call them a f@g when you drive by. They never chase you and it just feels great.

PTinVT · 12-20-2011, 05:03 PM

my 2c - Don't try to bring specs or physics to court, that's just going to piss the judge off. All that matters is how fast the cop thinks you were going.

Hire a lawyer who knows that court. Good luck.

John 070 · 12-20-2011, 05:09 PM

The only possible situation I can see 42 as being the end of the world is possibly in a school zone. I did 52 in a 25 and my first impulse was not to hire a lawyer, nor deny it. I did it. The question was how do I not get a 40% insurance surcharge which costs much more than the ticket for the next 3 years.

I think there was a case Fico v. Commonwealth where the accused combined his credit score and a metabolic panel to prove unequivocally that he was not fit to travel at the rate he was accused. There are so many ways to duck a question like that. That's what makes this the greatest nation on earth, it doesn't even matter.

Another way to look at it:
Acceleration = F/m, where F is the net force applied to a mass, m.
a=f/m,
acceleration in terms of velocity.
a = v - u/t Delta Velocity divided by Time.

A = ΔV ÷ T Acceleration is worked out by (final speed - initial speed)/ time taken for change in speed a = v2-v1/ t2-t1 Strictly you should say velocity ie the speed in a certain direction. Youalso have the formula f=ma which tells you that the force needed to get something moving will be the mass of the object multiplied by the accelertion you want to achieve; so from this formula if you know force and mass you can work out acceleration. The formula for acceleration is: Vf-(Vi)/t ie. change in velocity per unit time. Instantaneous acceleration in its differential form is d2x/dt2 where x is a function of time t.
Acceleration is the time rate of change of velocity.

That is, acceleration =dv/dt (v - velocity ; t - time)
Or simply acceleration = change in velocity / time

Cory1970 · 12-20-2011, 07:04 PM

Thanks for all the great information. I will be taking some street measurements tomorrow. Lucky there is video evidence showing a start and end point of acceleration. This will make it much easier to show a point of reference.

I will try to make a diagram and post it up.

Thanks

babbs · 12-20-2011, 07:18 PM

You can come up with all the data you want, but it will depend on you starting from a stop.

You: your honor, it is physically impossible for me to attain that speed from a stop in that distance.

Cop: maybe you ran the stop sign, say what you want, but you were going that fast.

Judge: guilty

chromisdesigns · 12-20-2011, 10:29 PM

If they got you on radar or laser, you're gone unless you can succesfully challenge the unit calibration, officer training, or something like that. If it's critical, get a lawyer. They don't have to prove it's "possible" for you to have reached that speed. They just have to show evidence (which they presumably have) that you were clocked at 42. End of discussion.

Absent some problem with equipment, you CAN'T prove it's impossible, the evidence contradicts you.
