QA: Driveways with access private that are connected to the public network

## Context

Driveways are areas where parked cars are disallowed. In some streets they are the only places where pedestrian can access the street (apart from formal crossings). As such, driveways can play a relevant role when routing for foot traffic.

However, driveways are usually private and sometimes have an `access=private` tag. This tag is sometimes applied to the whole driveways

## Mapping

The ideal mapping is
- split the driveway into a public and private part
- apply the `access=private` only to the public part, usually behind a `barrier=gate`

Example: https://www.openstreetmap.org/way/1016560485#map=19/52.368370/13.618816&layers=N

## QA

Show all driveways
- … that are connected to the main road / graph
- … and have access=private on this section (that connects to the main road)
- … and the main road does not specify a sideway:SIDE=no for the side of the driveway (in which case we would not care about the connectivity)

This might still show too many non-relevant driveway.
The once we are interested in are those, that create some form of connectivity to the other side of the road.
However, those are not mapped with connectivity in mind in OSM. For example, this case is mapped "right" as not connected but a pedestrian can use the way to cross. (Non-ideal example, because one side lacks a side-walk…)

Another example would be https://github.com/a-b-street/speedwalk/issues/26#issue-3703939875 which create the connection between a foot path (crossing) and a driveway (otherwise not tagged as crossing).

The call to action would be, to split those driveways and to remove the `access=private` from the part that is on public land/connects to the main road.

Driveways: Check if private and connect to main road – QA: Wenn service + private UND bis main road UDN main road da sidewalk, dann service an diese stelle non-private splitten – IDEAL: Nur weolche service roads die connecty herstellen wie wenn zwei aufeinander treffen oder einer auf einen fußweg / path trifft

该 issue 描述了一个针对 OpenStreetMap 数据的 QA 检查。仓库 'speedwalk' 是一个用于评估人行道制图的 Svelte 应用。研究可能涉及 OSM ways 的数据处理逻辑，筛选出带有 access=private 且连接到主道路图的 driveways。首先检查加载和筛选 OSM 数据的代码，查找现有的 QA 检查。确定如何评估连通性以及 'sidewalk:SIDE=no' 等标签。输出应为问题 driveways 的可视化结果或列表。
