In a recent update, Tesla seems to have changed Autopilot to make sure its cars obey the speed limit exactly while using Autosteer on surface roads and undivided highways. Tesla vehicles in Autopilot used to have a 5mph buffer in such situations, but that no longer seems to be the case, according to Electrek.

If the Tesla is on a highway, however, the enforced speed maximum in Autopilot mode is still 90mph.

In a November earnings call, Tesla CEO Elon Musk promised to restrict people from doing “crazy things” while they’re driving Teslas in Autopilot mode.
