There is a slight delay when sending commands over the internet from the Ctrl-Bar to your car. To avoid a degraded user experience, Ctrl-Bar has a screen in the center showing your real-time changes. If you, for example, want to change your temperature from 65 to 70 F, you would turn the knob five indents to the right. The screen will show your new temperature as you turn (66F, 67F, 68F, 69F, 70F). When you're done turning, it will send the new temperature to your car (in less than a second). This results in a great user experience with no latency as you turn the knob and press the buttons.
