> all the wrong characteristics for locatability of source

Glad I'm not the only one who has noticed this, I thought I was going crazy because in the majority of cases when I'm behind the wheel and I start hearing an ambulance siren I can't honestly tell from where it is coming from. I'm kind of aware of the general area, like it's coming from that general part, or that other general part, but I'm never sure until I actually can see the ambulance itself.
