I watch:
TeslaBjorn (Bjørn Nyland): I like his detailed testing. It's occasionally annoying that he'll seem to just try to figure out how something works instead of reading the manual, but since he seems to Always Be Testing, I can forgive him not wanting to read manuals.
He publishes a spreadsheet of his results and it has a worksheet called Banana. It's for his banana box tests, that test cargo space uses banana boxes.
Electric Vehicle Man (EVM): former Leaf owner, now Model 3 Owner. Tests a bunch of PEVs, including PHEVs. (His new car reveal video when he bought his Model 3 was very enjoyable. The contrasting reactions of his daughter and wife were great).
Both of the above understand the essentials of EVs.
Now You Know: despite being Tesla and Elon Musk fanbois, I find them entertaining, and they ooze passion for what they're doing.
FullyCharged: a terrible channel for regular car reviews, but they are very interesting for other topics.
I can't stand Doug DeMuro and something about Ben Sullins set off a mental alarm, so never watched Teslanomics.
