Non emergency needs are not an excuse for illegal behavior.
If it’s that critical that they remain close to their vehicle then they should plan better. I.e. a drive through, coffee shop with parking, thermos full of coffee, have two officers per vehicle and one stays with the car, etc.
While that’s a fair point, it’s not the only example of planning ahead. I’m sure there’s plenty of other ways than the ones I came up with in a few seconds.
They could also pick a drive throughs that have enough room to leave the line. Less common in cities but they’re still there.
Edit: I’d also like to point out that their lights and sirens are designed specifically to get people’s attention and get them moved out of the way. More difficult if you’re trying to get a vehicle 10 cars up to move but it’s not like they’re stuck waiting like the rest of us would be.
