It should be noted that drivers will experience a minor delay when using the buttons on Ctrl-Bar, since the app will need a few seconds to communicate with the Tesla. However, any changes made using the buttons will be reflected on the center screen. Drivers can use the scroll wheels to set their preferred temperature, while the four buttons can be programmed with a variety of shortcuts, including Seat Heaters, Dog Mode, Defrost Mode, Homelink, Open Trunk/Frunk/Chargeport, and more. The accessory even lets users cast bright LED lights onto the center console and front footwells.

Speed trap warnings will also be offered as a subscription-based service. When enabled, Ctrl-Bar will scan for speed traps close by and share visual notifications with the driver. If it determines that the driver is speeding, it will play an audio alert for the driver to slow down. The platform adds that the tool will constantly improve thanks to frequent software updates. Since Tesla drivers are the target market, it will also welcome suggestions on how to improve the user experience.

Apart from the potential benefits, there are some challenges for Ctrl-Bar. According to Greenmission, the makers of the product, the major roadblocks include the development of the smartphone app and figuring out how to maintain a steady connection between Ctrl-Bar and the connected phone. Despite these concerns, the project seems to have gained momentum on Indiegogo. At the time of publication, over $20,000 has been raised toward the total goal of $27,203 needed to begin production. Interested Tesla owners can choose from the $260 early-bird or the standard $270 crowdfunding options.
