It began a few years then tapered off, but in the last month I have come across 2 funeral cars with flashing corner strobes and purple strobe lights (they look red in daytime) "stopping" traffic at intersections to let the procession through the red light. One was even angled across the road. NO - you do not block the intersection. NO - you cannot have purple lights. NO - you can never, never, never, have flashing white strobes. Don't give me this crap about "well that's the way the cars come delivered nowadays". Two companies around Boston were identified as installing these lights illegally for you people. Stick to your purple and orange roof flags and hazard lights. It worked well for decades.
