In our neck of the woods, EVs frequently have accidents at 
intersections, especially within city propers -- so what i 
had in mind was giving the EV the ability to control the 
traffic flow while enroute to/from accident scenes -- the 
system would give opposing traffic plenty of time to slow 
and stop at yellow-to-red lights and give the greens to 
the EV -- so EVs would never have to slow down, and the 
EV-involved accidents would decrease in number --

As you may know, radio signals travel at a certain fixed
velocity -- so it takes a certain amount of time for them 
to travel a given distance -- so when a vehicle is a 
predetermined distance away from a traffic light, the 
transponder (perhaps if i use the term transceiver? to 
note that it transmits *and* receives signals?) will 
sense the distance -- this is an electronic version of 
the mechanical equipment used at most traffic lights 
today --

All a transponder does is transmit *and* receive signals -- 
your AM/FM radio only receives signals, where a transponder 
or transceiver also sends signals -- the transceiver in a 
vehicle would send a signal to the traffic light, the light 
would receive the signal and sense the distance -- then the 
light might send useful info to the vehicle such as 

   "light will turn green in two seconds" -- or 

   "opposing traffic closer to intersection - prepare to stop"

And if people were meant to drive, God would have 
given us wheels instead of legs?
