Glad we agree on this, the reasons you imagined could be true or false, the main point is that drivers are going to be affected by the bike lanes significantly more than by cyclists.
> Bike theft is not why people don't cycle
It is in my experience. E.g. I don't bike to work because the office building requires bikes to be stored in the shared storage room and I don't want it to be stolen. There is a bike trail between my home and office so no 35 mph cars you are so afraid of.
I think drivers are catered to in almost every single scenario in the United States to the point that giving cyclists any space, any infrastructure, or anything that is not also usable by cars is almost unthinkable. With that in mind, yes, drivers will be inconvenienced. Oh well. They're convenienced at almost every turn in almost every decision about transportation, let's give bikes a chance too.
You have a bike trail? Lucky! I live in central NJ, while bike trails do exist in the western part of the state, where people live here, they basically don't exist and you have to just ride in the street. Almost no offices even have a storage room, so you'd be chaining your bike to a sign, most likely, or storing it behind the building somewhere. You have it better than we do here...clearly, there's a lot more work to be done.

Yet it's reality in many cities in the US - tons of bike lanes, unusable by cars. You can bring up bike lanes on google maps, show me a city without those.

And yet, the bikes don't get stolen? Not even parts like wheels, saddles, lights etc? Lucky!
People don't bike here because they can't. I don't live in a city, I live in one of the many dense suburbs (which are denser than many cities in the US) of NJ, where there's lots of roads, and almost no bike lanes. Where biking does happen, they bike in the street, with no shoulder, and hope not to get hit by cars.
The bikes aren't stolen because there are no bikes, because you'd have to have a deathwish to try biking in the road with cars in the same lane as them.
It's the densest state in the union, and the only places you can bike are Newark, Hudson County, New Brunswick, Trenton, Atlantic City, Camden, the barrier islands, and the boardwalks. The other 99% of the state, you're putting your life on the line.
It's about safety. Would you feel safe biking in those lanes? Would you feel more or less safe biking where there are none?
PS. Your response got killed for some reason (very bizarre in an old thread and so quickly) but to answer your question - it depends on the road. There are roads I don't feel safe driving (I live in Austin, where the city decided that the traffic enforcement is racist or something so there is none, as the result there is mayhem on the roads) but I do bike on some streets with 35 mph and no bike lanes without feeling I put my life on the line.
I don't feel safe when I ride like that, I've been almost hit multiple times from people going into a turn lane or making a right on red because they didn't even bother looking (or just didn't care and got within like a foot of me to get into the turn lane). Most of the time, it's fine, but what would be a minor accident in a car is going to leave you pretty injured on a bike.
To paint the picture, imagine it's rush hour, and there's cars backed up everywhere because that's just how it always is at rush hour. You're, let's say, 7 cars from the intersection, and a cyclist passes. You see them for a grand total of maybe 5 seconds before they're too far ahead of you to see, then they turn right at the intersection, and they're gone.
Here's[1] a study from Rutgers about this, it seems to conclude that bike lanes do impede traffic, but the reason is that when a bike lane is present, drivers don't speed and actually come to a stop when making a right on red, and in general, the drivers in these areas don't speed when there's a cyclist there. Speeding does alleviate traffic, but I don't really think the safety benefits are worth it.
