Tesla aims to release major Autopilot improvements to vehicles outside the U.S. by March 2022. Given Europe's commitment to improving road safety in the coming years through a series of regulations requiring vehicle safety systems to be installed in vehicles, the timing of Tesla's release of Autopilot improvements seems perfect.
However, according to Whole Mars on Twitter, many Tesla self-driving car users in Europe complain that "the speed limit is incorrect, and the correct speed is not reached before the (speed limit) card is passed". In response, Musk responded on Twitter that Tesla's Autopilot team aims to make major improvements for car owners outside the U.S. around March, based on regulatory approvals.

Improvements to Tesla Autopilot in EU countries seem to have matured. Some EU regulators are developing mandatory vehicle safety system requirements for all cars sold and registered in EU member states.
In 2019, EU countries reached agreement on the General Safety Regulation, a new vehicle safety law. The details of the agreement set out the requirements for various mandatory vehicle systems.
In January 2020, eu Regulation 2019/2144 came into force, which stipulates that vehicles must introduce a series of new technical and safety measures. The Regulation will become mandatory in all EU member states by 6 July 2022. The Federal Ministry of Digital and Transport (BMVI) has set a detailed timetable for the implementation of the regulation, as shown in the chart below:
Next year, the Driver Drowsiness and Attention Warning System, the Intelligent Speed Assist System, the Advanced Emergency Braking System and the Emergency Lane Keeping Assist system will all be enforced. Then wait until 2024, every car sold in the EU will have to be fitted with the above technology.
Tesla Autopilot seems well suited to the EU's new auto safety regulations. The regulation also provides simpler, direct guidance for Tesla to obtain regulatory approval in parts of Europe, particularly in EU countries. Trying to comply with the regulations of each European country can be more complicated than complying with a set of rules in several countries.
