They aren't being antagonistic, they are protecting themselves. Allowing a motorists to pass you without leaving their lane is a really good way to end up dead and is also illegal on the motorists part. They are moving over to force the motorist to pass them in a legal and safe manner.
I felt like you just ignored the point of the person replying to you. Cyclists are in more danger from passing cars when they aren't in the middle of the lane, as they tend to get run off the road. When they are in the middle of the lane, the other car needs to perform the same passing technique they would normally do (exiting the lane and getting into the oncoming traffic lane).
The chances of you getting into a wreck for pulling over getting hit in a Tow Truck is in no way equivalent to a cyclist doing the same thing. You have visibility and weight.
As a non-cyclist, ya it can be a pain in the ass, but the cyclist has the legal right to the whole lane.
Which was ignoring my point above: "I've see people move into the middle of the lane for an approaching car so it won't pass, and when there would've been room to pass safely."
At least in California the law is:
"Any person operating a bicycle upon a roadway
at a speed less than the normal speed of traffic
moving in the same direction at that time shall
ride as close as practicable to the right-hand curb".
I get the safely part, but I'm talking wide separated lanes here, well over 14ft with weekend warrior-types trying to swerve in front of cars after having them behind them for a mile or two (no honking or tailgating). It's ridiculous and needlessly aggressive.
I'm sure there are tons of cyclist who misue these rules and are truly unsafe. Also, the Cali law isnt as cut and dry as you stated.
"A new bicycle lane change law was approved in 2022 and took effect on January 1, 2023, across all of California. Motorists approaching or overtaking a cyclist on the road must now switch lanes if another lane is available."
"In certain circumstances, cyclists may “take the lane” and use an entire lane, just as a car would. Riders may claim a full lane if they are passing, readying for a left turn, steering clear of an obstacle, or if they feel the lane is too narrow to share with a car"
Once a law leaves latitude for how someone was "feeling", it effectively legalizes the practice in almost every scenario.
>If I'm driving well under limit due to towing, looking for address, etc - I pull over and let people pass. It's not so hard for a bike to do same.
Thats cool! It's also not hard for motorists to wait literal seconds to safely pass a cyclists. Cyclists shouldn't need to pull over all the time to accommodate motorists need to speed down the road. You aren't entitled to go 10 mph over the speed limit. It's a limit, not a minimum.
>I've also seen bikers upset when a kid is going slowly in a bike lane? So I think many of the spandex-clad dudes have some control issues.
Wow! You did? Crazy! It's almost like a group of people with a shared hobby aren't a monolith and will display different opinions and behaviors!
I think these folks are the ones giving bikers a bad name by being antagonistic to prove a point.
