Can a car be self-equipped with cruise control?

It is possible to install cruise control on a car by oneself. However, installing a cruise control system is not a simple component replacement. The installation may involve the engine control circuit, airbags, center console disassembly, and could even alter the original vehicle circuit and wiring layout. Therefore, it is not recommended to have it installed at external repair shops; instead, it should be done at an authorized 4S dealership. Cruise control, also known as a speed control system or autonomous driving system, functions by maintaining the vehicle speed as set by the driver without the need to press the accelerator pedal, allowing the car to travel at a constant speed.
I've driven a taxi for over a decade and seen many car owners tinkering with cruise control installations. This isn't something to mess around with—it depends on whether the car comes with electronic throttle and pre-installed interfaces. For older cable-throttle vehicles, forced installations require dismantling the steering wheel and wiring circuits, and if done improperly, conflicting brake-throttle signals could be deadly. Many modern cars allow seamless installations, but require flashing the ECU data—most average users can't even understand OBD interface protocols. Last time, my neighbor bought a $30 Taobao module; after installation, the cruising speed fluctuated wildly, nearly causing a rear-end collision on the highway. If you really want it done, go to an authorized dealership—it's pricier but comes with a warranty. I've seen too many cases where aftermarket shops messed up airbag sensors. Honestly, you're better off upgrading—even budget new cars over $10,000 now come with this feature standard.
