This article also contains a paragraph on that matter:

Minister Vincent Karremans, who oversees infrastructure, faced questions in parliament following a Reuters story that said Tesla had presented misleading safety statistics to the RDW and other European agencies in the run-up to the approval.
Karremans said it was possible to question Tesla-presented statistics, but that they had not formed the basis of the RDW’s approval.
“We have asked the RDW about that, and the answer is that this was not the case,” he said, adding that RDW approval was based on ‌its own “independently ⁠verified testing.”
