Block the flow of traffic. Vehicle traffic has predefined rules to deal with this and it happens all the time. Now you're forcing pedestrians to go onto the road creating a safety hazard. Strollers, like with OP, or disabled people or really you name it are severely disadvantaged by this, just because this person needed a gigantic car thought vehicle traffic was more important than pedestrians.
Apart from this being completely stupid. Why don't make dark mode the default mode?
