Is the car's own cruise control worse?

On every supported car openpilot steers. Whether it also controls speed and braking depends on the exact car. Here is the answer by brand.

openpilot sets the speed and following distance, slows for traffic, and can stop and go on many cars.
openpilot steers while the car's adaptive cruise handles speed. You set the speed on the car's own buttons.
The car's cruise is used by default. A hidden openpilot toggle exists on non-release software, and comma calls it alpha.
Counts come from comma's official car list. Open a brand to see each model and year with its answer.

Sometimes. Forks such as sunnypilot add speed control on cars where stock openpilot leaves it to the car. Check that fork's own car list before you rely on it.
Every row is read from one exact version of comma's official supported-cars table for stock openpilot, checked on 2026-10-19. Community forks can differ.
