I have a huge problem with funeral processions for a number of reasons:

1. People get killed by them and in them.  Why?  Many states don’t have laws regarding the procession, whether they’re supposed to be marked or drive with flashers, or have a police escort, or whether the lead car or any behind it have to stop at red lights.  Unless you’re in front or behind one, you may not notice the flashers, but you would notice a flag in the window, although you might assume they’re all fans of the same football team heading to a game.  For the record, there is no law any of the 50 states requiring you to pull over for a funeral procession coming at you from the opposite direction.
2. The custom of pulling over for funeral processions approaching you (driving toward you & going in the opposite direction of you) is dangerous idea.  You can have an accident by ramming the rear of someone who sees a procession before you and slams on the brakes to pull over, or someone ramming you because you slammed on your brakes to avoid hitting the idiot in front of you, and when you try to get back into traffic, or you hit someone who’s trying to get back in traffic, or someone hits you on the side of the road.  All for somebody you don’t know and that you would’ve attended the funeral if you knew & cared (more about this idea of respecting dead people & their survivors that we don’t know below)
3. Pulling over for funeral processions is a ridiculous antiquated idea as it’s ridiculous to show respect or feel sad for people you don’t know.  I know that sounds bad & cold, but consider this — think about the people in the world who die every day.  Do you think about them often, or at all?  What about if you’re on vacation 2,000 miles away and while you’re in a coffee shop, you spot the obituary page of the local newspaper open,  Do you read it, and do you feel sad for those people & their survivors?  Of course not, because you have no connection with them.  If you got sad at every person who died and their families, you’d have no time for anything else as on average, a person dies in the USA every 12 SECONDS, which is 5 per minute, 300 per hour, and in 2018, 7,700 per day average for a total of appx 2.8 million people per year, and that’s just in the USA and only verified deaths.  If you’re getting sad every 12 seconds, you’re staying constantly sad and you have a mental problem, and if you aren’t, but you feel people should feel sad for complete strangers, then you’re a hypocrite, and if you feel you should be sad for only those dead people that cross your path, then you’re a narcissist who feels that it’s only important because it’s happening to you, or you’re still a hypocrite as you’re only showing fake sorrow because you’re being observed.

The whole idea of a funeral procession is a stupid idea.  Just tell people where the funeral is and let them get them on their own.  This is 2019, and anybody who doesn’t have Google Maps on a smartphone or GPS in their vehicle or can’t follow a road map you drew is a moron who needs to try to find their way home anyway & skip the funeral.  Nobody needs to follow the dead person — they don’t know you’re doing it, and if you think they’re looking down upon you from Heaven, well that’s not only a whole different argument about fairy tales vs reality & science & psychology, it’s also optimistic on your part that your favorite uncle isn’t looking UP at you from Hell for something screwed up he did that you don’t know about.

Even the idea of burying dead people in the ground is ridiculous.  I get the monument thing; I know you want people you loved to be memorialized, and we want the graves of celebrities to be monuments to them as well, but we can have monuments without the graves.  We can even put them in public parks so they will be maintained by local government & people have a chance to see them on a more regular basis without the thought of stepping across dead bodies to do so.  Cemeteries are the biggest waste of space in the entire world, even more than golf courses, which is at least something paid for and enjoyed by people.  Many cemeteries go under financially and turn into desecrated open graves amid unkempt grounds.  There is no need to save dead bodies, and burial costs are prohibitively expensive.  All people should be required by law to be cremated, no exceptions.  The reasons behind burials are just more antiquated religion reasons that have no business existing in a civilized, intelligent society in 2019, and they’re perpetuated by the for-profit funeral business & religion who take their pound of flesh from it.
