Per Oren:
I'm not the one to complain to. Maybe tell your community leaders to
refund your tax dollars for safety devices on public service vehicles
or infrastructure.

Here's something form what *seems* like a credible source - which seems
to downplay the utility of lights/sirens on EMS vehicles:

A few clips:

"There is an over reliance on the ambulance sirens to alert drivers of
other vehicles to the presence of emergency vehicles. As a result,
collisions occur every day with tragic outcomes. "

"A Department of Transportation report concluded that sirens will never
become an effective warning device."

"The use of lights and sirens while transporting a patient has come
under scrutiny many times over the years. While this seems to still be a
come practice in the year 2010, many studies have shown that this is of
little value in the patient’s outcome. Most of the research that has
been completed on this issue dates back to the mid to late 1990s."
