openxc/openxc-vehicle-simulator ? reverse-engineered prompt

Build me a local web app in Python that simulates OpenXC vehicle data in real time, so I can use it for testing an Android app.

I want a browser based dashboard on localhost where I can change things like throttle, brake, steering, gear, doors, and lights, and see the simulated vehicle signals update live as I move them. It should generate plausible car data continuously, not be a racing game or a super accurate car model. The app also needs to listen for a TCP connection from an Android device running the OpenXC Enabler and send the simulated data to it.

Please keep the UI simple and practical, with sliders, toggles, and live readouts of the outgoing values. If there are any setup details or current library changes that matter, look them up online if you need to.
