sound radar is back ... naaaaaaah!

At same speed there would be no approach.

Again, your audio apparently supersense is imho not necessarily a good basis for comparison

And then a car or a bike at 110 is barely comparible to a fighter plane that flies at much higher speeds and with much more hp ...

A plane engine is also not at the same frequency band and don't forget the bandwidth audible by the normal mortal human being is limited ...
