Taking the lane (vehicular cycling) often works well in slow-moving traffic, but it breaks down in when there is a large speed differential between the cyclist and car traffic. Effectively, you are in the way and drivers won't expect you to be there.
For these faster roads it is necessary to have dedicated cycling infrastructure, including Dutch-style safe intersections. Otherwise only risk-tolerant or desperate people will cycle.
It isn’t like I am invisible. Drivers routinely merge for a bus or ubereats vehicle or other obstruction. It is certainly safer than the alternative of not taking the lane and having these cars with the speed differential try and pass you in the same lane as you. This is what always happens unless you take up space and force the lane change to merge.
