They can. But do they? Comma can collect from any vehicle, regardless of type.
There's also a matter of deduplication where they really don't need to use ~250 days a year of the same commute. They probably have more data than others, but I'm asking for a proper confirmation of this common knowledge.
Tesla's vehicles lack the advanced sensor suites of other manufacturers, which means that Tesla's moat amounts to a massive quantity of lower-quality data. When it comes to navigating using lidar and radar, they're dead last.
