Hugh parades? How long does it take for an average procession to pass? 20-30 seconds? I couldn’t tell you how many processions I’ve seen and been in myself and I’ve yet to find one that took longer than a minute to pass, even when I lived and worked in Northern VA.
As for the idea of getting a map and allowing everyone to drive to the cemetary according to the traffic laws, I just have to note that most areas, including most urban areas, have laws allowing for funeral processions with police escort, so your complaint that funeral processions don’t follow the traffic laws is moot.
I didn’t say the funeral parades were illegal. So it is inaccurate to call my argument moot since I didn’t make it.
