UPDATE: Tesla is ending one-time FSD purchases in the Netherlands on May 15, 2026.

Y'all have two weeks to buy FSD outright for €7,500 before it's gone forever. After that, you'll only be able to subscribe for €99/month.

@DavidMoss @wholemars @fsd_database @TSLA_inside_ @ronald_termaat @EpicHaddock310 Would have been a lot more of FSD wouldn't stop at the border...😔

[Mark Sleijser @Sleijser]

@TSLA_inside_ Somehow good to hear that there are more people waiting. I'm also still on 2026.2.3 and checking for the update more than I like to admit...

@SawyerMerritt The most entertaining outcome is the most likely... @elonmusk said that the Roadster would be launched on April 1st. Elon Time could delay this to April 20 (4/20). While showing the SpaceX package on stage Elon announces the start of a marriage of @Tesla & @SpaceX Just a thought

@Alexandra261074 @Belastingdienst nee nog niet, telefonisch kon men ook (nog) niet helpen. Morgen weer bellen als de wachtrij bij de betreffende afdeling minder dan 45 minuten voor sluitingstijd is ivm de wachtrij...

[Mark Sleijser @Sleijser]

@Belastingdienst Nee, gewoon via browser op de computer. Had de stappen van de online hulp al geprobeerd maar dat werkt helaas niet (zowel met Chrome als Edge).
