But Google Maps vans cover land comprehensively, whereas Tesla's "convenience sample" is not comprehensive. However, Tesla's data then covers the relevant data more often.

Definitely two data sets that should be put together.

But they intentionally don't cover the same ground frequently, which is a key part of the Tesla data. The same intersection in many different conditions is pretty important.

I'm assuming that once a Google Maps van has covered an area, it intentionally avoids that area until a significant time later.
