I agree that they change traffic flow. But it is interesting there's an implicit car-prioritization bias in the behavior you're describing.
The delivery/service vehicles choose to block the bike lane instead of blocking a lane of traffic.
This gets complicated quickly once you factor in total impact and so on, but I just want to point out that a person on a bike doesn't necessarily deserve less priority than a solo driver, for example.
Plus there's the fact that blocking the bike lane is indeed illegal as noted by the other commenter. Although I sometimes think that we don't really know how bad it would be if all delivery drivers had to comply with all parking laws - maybe we'd all be starving in the nicely flowing streets due to a lack of food.
