Stupid things PETROL HEADS say

Any measure of MPG that's "on a run" (?!)
It's RWD so that means it handles (like a Morris Marina)
Judging all cars against your own and declaring them to be inferior
Attempting to use maths to defend a car that has bugger all torque
"Only needed routine servicing".
In America, a "kill" (when you out-accelerate someone who probably wasn't racing you), this is followed by loud emotional celebration.

What you see a for sale add and they mention 'pulls like a train'
Really? Does it?
I'd add to that "nothing for one of these" to justify high mileage; I bet it's something if those miles were on the same oil/filters.Really? Does it?
And "bulletproof", how the hell did you discover that??!!

Toy
If the car is a total indulgence and does few miles every year for no purpose other than entertainment, how would you describe it in a single word?Small plastic figure that resembles a human (of sorts)? A doll.
What do you call small modular blocks that attach to each other and will one day take over the world? Lego.
What are they collectively? Toys.
Should a car be frivolous and fun, a car used SOLEY for entertainment - yes it is a car. In the same way that Action Man is a doll (or action figure if your masculinity is feeling threatened).
However, the collective noun 'toy' is perfectly applicable to a car as described above.

if you lose your keys get someone to call your mobile, hold it by the lock as the spare keys are plipped by the caller and the car will open.
You know that actually works, right?It shouldn't work as the frequency of the key fob is outside of the operational frequency of the mobile phone microphone and speaker, so the phone couldn't reproduce the key fob signal, at least, that's the theory, more or less.
I will admit to never trying it, so can't say for sure.
I do know, however, that you can use your skull as a passive resonator to increase the range of your key fob by holding the fob to your chin.

That is nothing to do with the theory unless you have an incredibly weird remote locking system that works on sound!!!!!!It shouldn't work as the frequency of the key fob is outside of the operational frequency of the mobile phone microphone and speaker, so the phone couldn't reproduce the key fob signal, at least, that's the theory, more or less.

"A Civic Type R has no torque, and it would be a chore to drive on a daily basis".
Of course....
Similarly I've read the "not enough torque for town" comments. I've had people genuinely question how I can possibly drive a car with 116lb-ft. Of course....
I own an Type R and not once have I ever said or heard "vtec kicked in yo" being used seriously...

Well, the audio frequency range is up to about 3000Hz. A mobile phone speaker should work at a much lower frequency. A keyless entry signal is coded on a 430MHz carrier, so I can't see how that could be picked up by a microphone that is used to transduce voice frequencies.
Edited to add: I'm not sure if we are agreeing or not!!
Radio waves ARE NOT sound waves.Edited to add: I'm not sure if we are agreeing or not!!
You are right but for the wrong reason.
Even if the microphone could pick up sounds at 430MHz it wouldn't help because RADIO waves at 430MHz don't move AIR around.
Seriously chaps, this is a pretty fundamental difference here.
It is the equivalent of trying to show someone a photo via a mobile phone by holding the picture to the microphone.
Or trying to show how hot something is by holding it to the phone.
This is the EM spectrum. Note he has sound waves shown separately because - well - they have NOTHING to do with EM.

In practice, mobiles probably do pick up radiowaves because the wire from the microphone to the ADC will act as an aerial to some extent. It's still not going to make it across the mobile phone network though and even if it did the receiving phone would have no way to transmit it to the car with anywhere near enough power to be picked up.

Oh yes this! I have no cluewhat the hell anyone is talking about when they start quoting E numbers.......
- W211 by the way. I had to google that before a smart arse came along...

Hmmm - I am not sure you 100% get it.Mobile phones talk to each other over a variety of frequencies say 800MHz for example.
If remote locking ALSO worked on 800MHz then by coincidence it MIGHT be possible to randomly open cars using your phone. But the proximity or not of your remote fob to the person on the other end of the phone would be utterly irrelevant. It would just be that while sending lots of RF out on the 800MHz band - the phone might stumble across the exact sequence needed to unlock your car.
(This is part of the reason why they are on separate frequencies!!)
Of course all the wiring in a phone is acting like an aerial for many EM signals.
AND a phone has plenty of power - enough to unlock a car. Just compare the relative size of batteries between your remote fob and your iphone!
But here is the point.
Phones don't unlock cars USING A SPEAKER. Speakers MOVE AIR. Your car doesn't have a microphone waiting to hear the right notes!! It has an aerial. (NOT the sound system aeriel either - that is different again.)
It would be perfectly possible for a phone to be designed to retransmit a 430MHz RF signal - but it would need to use its RF transmitter - NOT it's speaker to do so.
What has the frequency of the mobile network got to do with the frequency of the car remote? They're opposite sides of an ADC and a compression algorithm.
In fact I don't see what anything you said has to do with anything I said.
If a pair of mobile phones could perfectly reproduce the microphone signal they received, it would theoretically be possible to do as described. Your microphone wire would pick up the EM signal, it'd get transmitted as-is to the other phone whose speaker wire would then act as an aerial to retransmit the exact same EM signal at the other end. Of course in practice there are all sorts of reasons why it wont work, the most obvious being that the digital encoding and compression used on the mobile phone network makes absolutely no attempt to reproduce anything of that sort of frequency and even if it did the power of the signal generated at the other end wouldn't be anywhere near strong enough to actually be picked up by the car.
Still, you can see where such an urban legend could have come from.
