Maybe in a small rural town, this would be ok.
I live only 1/2 mile from a large cemetery, and it services a lot of the area of Orange County just below Los Angeles.
If I pulled over for every funeral procession??? I'd never get home. And, yes, they have to run funerals whenever they have the time and scheduling. I understand that. But when you are talking 200 cars, you are talking a jam-up that lasts 3 or 4 streets, and our streets are HIGH TRAFFIC volume.
I'm sorry if people are tush-hurt when I don't bother to yield to their procession. But lest's be real here: This planet has some odd 7 BILLION people on it. We are not stopping for every person who passes on. It's just the nature of the area you are in.
When I die and am done? I'll be cremated, and they can take a leisurely boat ride out to open water, so I won't be a traffic nightmare for everyone else to endure. Cast my ashes, have a beer, and go fishing. I'm done, get the farewell party started, and enjoy the life you have left.
This said; I do make a point of getting out of the way of a funeral procession in a quiet place, a small town, etc. If there is room to move over and wait it out or step out of the way?? I will do that, for both them, and me. Just don't expect it on Beach Blvd. on a Saturday morning at 10 am. Not going to work out like that......
