most do that IME
I had to pull out into traffic once last year, and didn't like it. There was literally no other option, nowhere else to go. Going back down the lane I came from wasn't a legal option, and there was nowhere else. Sitting & waiting, my usual tactic in such sitations, was clearly not working or going to. I've avoided that turnoff since.
I don't mind excusing drivers of ancient cars doing that. In modern traffic it's often the only way they're going to get out, other than waiting hours at each such junction.
