get_user_pages() also honors copy-on-write (CoW) semantics. If a write is detected to a non-writable page table entry, an “page fault” is emulated by calling handle_mm_fault, the core page fault handler. This triggers the appropriate CoW handling routine via do_wp_page, which copies the page if necessary. This ensures that writes via /proc/*/mem are only visible within the process if they occur to a privately shared mapping, such as libc.

反思失败尝试，我一直在解决原版根本无需考虑的问题。车辆不需要路径寻找，因为地图会告诉它们可行进方向；碰撞检测成本低廉，因为提前终止逻辑使大多数检测近乎免费；不需要速度或物理系统，因为每帧1像素的移动已足够逼真；即将碰撞时暂停10帧，需要转弯时只需移动半个地块宽度即可转向——这套规则适用于任何场景的任何地块。
