    Took a brief spin after installing 2020.36.3.1 today, and was both pleased and disappointed.

    As hoped, the car now reads speed limit signs and sets that speed for Autopilot.

    As feared, the car does not read the “End of speed limit” signs commonly used in Vermont, where I live. Vermont has a “default” speed limit for paved (50) and unpaved (35) roads. So most areas other than interstates just set up zones to deviate from that, ending the zone with an end of zone sign rather than a new limit.

    Result: this potentially great feature is going to be useless on non-Interstate roads in Vermont.

    It's the first iteration of the speed limit please be patient.

    This is why it is called a BETA feature. It needs time for the machine learning algorithms to improve and was clearly stated in the release notes.

    There are so many redundant and ridiculous speed limit signs. I don't think there's any national standard for speed signs, so every state just does their own thing.
