Telsa's biggest threat in the European market is the Volkswagen Group with deliveries of its ID.3 in Norway, albeit a relatively small market but a major one for EVs, having exceeded deliveries of the Model 3 for 2020.  It's even more remarkable when one considers that the ID.3 only went on sale in Norway on September 15th.  Audi's e-tron has also made significant inroads against Tesla in many markets in the EU.  

The ID.3, in numerous published reviews and YouTube posts, has exceeded expectations with a solid automobile.  This proves that not all of the market is fixated on the fastest accelerating vehicles in the respective classes.  Here's an YouTube comparison of the ID.3's advanced driver's systems with the heavily discussed Tesla Autopilot.
