Not a clump, but it happens more often than I would believe if I didn't see it so often...
When I come up behind someone on a curvy road going slowly, usually a cager, they see me in the rearview and suddenly want to show me how fast they can go. Looks so stupid. So I have to back way off to keep the moron from running wide in the turns... hanging way back until their blast of testosterone is finished. So dickless... or maybe they just don't have anything better to do. .............
Well, I figure it's them being nice. I'm not in any particular hurry, just having a little fun is all. But yeah in the unusual event that they start to ping-pong the lines or cross, I do the same thing.
Some folks merely slow down even more. I don't want to speculate whether they're doing that in an attempt to annoy someone because I'm not in their heads. I've had some pull over and wave me around. Too nice... didn't ask for it (riding bumper, flashing/waving headlamp, weaving the lane, acting a fool, etcetera...) or expect it.
And then there's the complete asshat that decides he (yes, it's usually a 'he') wants to show how fast he can go after I pass him. He's tooling along, minding his own business, so I pass as safely and briefly as I can and then I see and hear Cletus giving it the beans to show me that he shouldn't have been passed. (?)
It's not just bikes though... one night, driving my diesel pickup on a backroad with a few passing zones, came up behind another truck driving slowly. As soon as I hit the long passing zone, I went around. As soon as I was ready to pull back in, where's that truck? He had floored it and was right on my flank. I pulled back in right in front of him and the guy rides my ass hard. I'm not taking my diesel truck to the races, so two or three turns later, I just pulled over. Have no idea what that dickweed's issue was. So yeah, it's not just people on bikes.
This, this, this. Yes... wwaayy too often I see this happen with others, and have had it happen. When I notice someone passing me on a single lane, I slow down to let them back in sooner... not try to speed up and create a head-on situation. That's just not cool. I don't own the road, but there are some that like to pretend they
Had one pickup with three lanes of late-evening easy traffic doing 70mph, decide he wants to do 71MPH in the far left lane. Not a soul in front of him. There are no left-hand exits along this highway. So it takes him a good 1/4mi to pass one vehicle and by the time there's enough space for a safe lane-change, there's another vehicle ahead. Didn't want slalom through traffic to get around so I just hung back and very patiently waited. After very patiently waiting for several exits, finally got an opportunity get around. I signal, slow lane-change, start to come around and the nutball speeds up. So I speed up, signal, make it around, then slow down to 80/75 depending on conditions. But now he's all of sudden in a hurry and are looking at GRILL in my rear-view for the next couple of miles. Didn't brake-check or drive any differently, I just ignored him. Apparently he was getting that close to phone in my plate because he only backed off about a 1/2 mile before there was a cop standing on the side of the road outside the car. Probably told the dude I just ran him off the road or something.
The lesson they've taught me is, when you pass, P-A-S-S
... pass them like they're sitting still. Don't even give them the possibility of entertaining a challenge. By the time they drop a gear you're already a vehicle length ahead and getting back over. It seems rude as **** but it keeps the road games to a minimum.
