SVOboy - oh ok. Those vehicles use much larger systems, which add significantly more to the vehicle price. This is why you don't see this technology on typical passenger cars. But to answer your question, it works in similar manner but on a lower level - it can handle a leak of around 5-10 psi/hr depending on speed for typical tires, but not enough to actively compensate for load changes, etc like with the H2.

Bicycle Bob - that is an interesting comment - that you would only like one, for problem tires. I/we are working on a version that would screw on to the valve stem from the outside, but it kinda sticks out, and is not physically appealing. I would think this type of device would work perfectly for your single tire use, but would likely not be the standard version.

And there would be a pressure management system that keeps the tire at a specific pressure, which would likely be settable to the pressure you desire. The max pressure would probably be about 40 psi. This system could keep it at the same pressure regardless of temperature.
