They give tickets for that here too. I've never received one because I don't do stupid shit like that. While you're pealing out you might just be a little less in control of your vehicle, and for no good reason.

Why is accelerating quickly "driving like an asshole"?

If I want to floor it everywhere I go, I should have every right to do so.

With my Insight, I find employing the 1-2-5 shift sequence to work well. The idea is that the engines volumetric efficiency is maximized with the throttle butterfly fully open. You reach cruising speed at maximum efficiency as quickly as possible, maximizing overall fuel economy.

If a cop ever pulled me over for it, I'd be fairly upset. Clearly, a display of acceleration.. all 73HP of it. :laugh:

It's not so easy to prove other than word of mouth... and even then, it's iffy. If it's your first offense and brought to court it would probably be thrown out.

VE is maximized, but so is power output...and developing 73 HP efficiently is worse on fuel than developing 30 HP inefficiently.

Without knowing the situation we can't say for sure, but if the OP didn't chirp the tires I don't see the problem.

You can fight it, but I hope you lose, frankly. If you want to be a racer, go do that on a closed track. Better yet, go hit the freeway; you can reasonably have a high acceleration on the on-ramp.

Actually, an engine is most efficient at wide-open-throttle (WOT). By and large, the gains in efficiency from WOT operation negate the losses from higher RPM from not short-shifting. The most efficient way to accelerate though is WOT and short-shifting. So WOT to 2,000-3,000 RPM (depending on the engine and how widely spaced the gearing is), then upshift.

That said, if the OP broke the tires loose at all then it's a slam-dunk win for the prosecutor. You just don't get to chirp the tires on the street.

You know, some people actually watch the intersection as well as the light and can easily see if someone's coming while accelerating hard from the stop once they verify that it's all clear. If you find that you are surprised by pedestrians or red-light runners then you need to start paying more attention to what's going on around you when you drive.

Welp, in principle I concur however one must assume that one who is crossing an intersection has checked for traffic (ergo, the signange is nigh irrelevent).

I got pulled over for passing a cop once. I quickly pointed out that he wasn't doing the speed limit. He said some BS about it didn't look good. I tried not to laugh, of course he let me go.

I hates it when drivers slow down when les flics are around -especially if they (les flics) are essentially breaking ze law. Maintain speed mofos!

You were accelerating fast, eat the ticket, cops word against yours. Just be careful where you play with your car next time.

You're ignoring the fact that it takes a lot more fuel to maintain higher acceleration, even if you're accelerating for less time. Consuming fuel more efficiently while demanding more power (not to mention taking your drag from a linear to a quadratic term) does not mean you are consuming less fuel overall. You are decreasing your fuel economy by peeling out at the green. You need to come to this realization.

The engine is most efficient at that point, but overall you still consume more fuel. Higher speed = higher drag = more fuel spent. Higher acceleration = more fuel spent. You do accelerate for less time, but now you've murdered your efficiency via more drag over the distance you travel. Even assuming significantly less efficiency at lower accelerations, to second order you will come out ahead in fuel economy overall. I took a thermodynamics course where we calculated the overall difference in fuel consumption between the exact cases we are describing now.

Run the simulation yourself, or hell, do it empirically, I don't care. If you're going to rely in theory, at least recognize that there's more to this than engine efficiency.

You've taken into account a second-order factor that boost fuel economy and ignored the dominating terms that significantly reduce fuel economy.

My dad used to get theses bullshit tickets years ago in his Camaro. "Exhibition of Speed".

Edit: He used to tell me it was the same cop all the time, too. Same cop who also wrote him a ticket for having no mufflers on his exhaust, when they were out in plain sight as he had side pipes.

Unless he can prove he wasn't accelerating fast (very difficult to do) and the cop says he was, well then you can figure it out from there

The cop needs to prove by a preponderance of the evidence that he is guilty of what he is accused of. Innocent until proven guilty, not guilty until you can prove your innocence. This is the US we live in, didn't you get the memo?

The criminal justice professor at university of Wisconsin Milwaukee admits to accelerating very quickly in that cops cannot ticket for acceleration. Take this to court.

So did the OP peel out or something if thats the case its exhibition of speed and not much you can do about ticket.

Was there a sign nearby saying "ACCELERATION LIMIT 25 FEET/SEC^2"? If so the cop may have a point.

People get irrational in traffic. The sound of a high performance car triggers every road rage gland within a 100 ft radius.

Really? So I don't have to pay speeding ticket I got saturday night unless the cop has a picture of the radar with my car and the speed on it? Frikin awesome.
