The best case time of the setup-with-retry stage that runs in most of our CI jobs is ~1m4s. All it does is setup the openpilot environment, and most of that time is pulling an already built docker image. This puts a hard limit on how fast our jobs can finish; a job that finishes in 1m is 10x better than one that finishes in 2-3m.

Some possible strategies:

• make the docker image smaller
• move the docker cache somewhere faster
• ditch docker, install directly on the 20.04 runner, and cache the apt and pip packages

Requirements for the bounty:

• all setup-with-retry on the final PR commit must finish in less than <20s
• must run on the normal free-for-open-source GH actions runner

Sub-bounty of $100 for <40s if you can't get to <20s. $500 is for <20s. Bounties don't stack.
