That animation shows a relative emitter to wave speed of roughly 60%...

Yes, and if a Harley could reach a reasonable percentage of the speed of sound in air you would have a point. Let me guess, you also worry about time dilation while flying in a jet?

True, the Doppler effect ‘diminishes’ the sound of an approaching vehicle at speed. However, to really get out ahead of the wave, you need some high mach numbers. It’s rare to see a Harley moving over mach 0.15 and I’ve never personally seen one exceed 0.2.

What you are describing has nothing to do with the doppler effect. You hear them better behind them because the exhaust points backward. It’s the same reason you hear a trumpet better when its bell is pointed at you than when it’s pointed away.

People only hear Harleys after they have passed because the tailpipe - from which said noise emerges - points backwards. This has nothing to do with the Doppler effect and everything to do with the direction of sound emission. In fact, your illustration uses an omnidirectional point source, rather than a highly

That’s an object going near the speed of sound. At normal speeds the doppler effect isn’t going to prevent people in front from hearing things.

Edit: I think it has more to do with the fact that the exhausts are facing backwards, so most of the sound is directed backwards. If you bend those so that they’re facing

Here’s a crazy idea: what if the radiator also functions as a coolant-to-fuel heat exchanger? If the fuel needs to be evaporated before combustion, wouldn’t that be easier if it were heated first?

And negatory on the cost of this mo-chine there, Red Ryder.
You might say I went right up to the factory and picked it up, it’s cheaper that way.

If they pulled the lifters off the valves, I can see it working. It’s just a plug to close off the hole. An SBC will run on 7.

Guernsey has a bunch of WWII bunkers, they’d probably do ok. (Guernsey along with the other Channel Islands were invaded by the Germans in WWII, which might be why this car was buried)

MO-PEDS, MO-PROBLEMS am I right??

It is the responsibility of the original owner to remove all logos from the vehicle prior to sale/disposal.

Can we stop saying stuff like this disregards the laws of physics? THE REASON THIS WORKS IS BECAUSE OF AN IN DEPTH UNDERSTANDING OF THE LAWS OF PHYSICS!

It’s obvious your passion has clouded your reason, assuming you had any, of course. By your rant it’s clear that you have no filter, you don’t hope to persuade anyone to whatever belief you subscribe — preaching to the leftist choir? Good for you: you used more profanity than the average writer, and managed to use

Yes, my driver’s seat selfie is killing my love life. And every other picture of me. And my appearance. And also my personality.

That’s why I call them marker lights like a good chunk of my midwestern region does. If you can’t see parked cars at night without their “parking” lights on, you shouldn’t consider driving at night.

Especially in rain where headlights reflect off the wet ground and you can’t even see the lines on the road.

There’s probably be about 3 people in the United States that would be confused if they saw a 1/2 ton truck doing 65 on the highway with amber lights on, let alone the fact that the white fog lamps are on as well. No one uses parking lights for parking anymore...kind of the point of the article.

Is that a space horse proximity gauge on the dash?

He became The Joker after he was rejected by a girl. Because he’s a NICE GUY!
