and honestly i have the same problem with that intended use. it often looks like a stopped car is attempting to turn out into traffic. IMO emergency lights should have a faster blink pattern or something to differentiate from turn signals.
Faster blink is already used to indicate that one of the lights is burned out. It's a consequence of the mechanical part that operates (used to operate) the blinking; less resistance caused by a burned out light means it blinks faster
There's a programmable flasher relay that does exactly this. It's specific to certain Toyota/Lexus and Subarus from the 2000s to mid-2010s, but it's something. I have one in my 2008 Sienna - the "emergency flasher" part is programmed to strobe, kinda like a tow truck. I like it.
