Remind me not to drive a vehicle where you implemented the control systems.

This is a great example of a little knowledge being dangerous. There's a reason control systems are not implemented the same way as a browser DOM. There's a reason control systems are designed to avoid subtasks, conditional execution, interrupts (as much as possible) and complex data models. The reasons are pretty damn solid, IMO.

Conceptually, you can talk about the two domains as being somehow equivalent. That says nothing about the appropriate implementations.
