Then you understand how people choose who they regard as experts, knowledgeable, and credible.
It's interesting to watch - it almost always ends up as:
a) "he hurt my feelings"

d) "I don't think that will happen to me"
e) "that costs too much"
f) "A guy on Youtube said otherwise"
g) "someone said something might work, which I think will, so am done and am moving on to other stuff"
h) "I'm never going to crash this car"
i) "I have a better idea than 100,000 automotive engineers before me"
j) "I now know enough to do this and don't have the time/motivation to learn it in any depth"
k) "The comments section on my youtube channel will point out my mistakes and erroneous procedures/thinking"
l) "block him, he's an a-hole"
m) "I got nuthin', so let's get him on "hands-on" stuff he rarely talks about, but strangely seems to know - must be in a book somewhere and my three hours in my garage trumps dat chit"
o) "I don't like the answers here, so I'll shop it around to OIF, Reddit, etc until I get the answer I want to hear"
p) "I don't like Player A so always side with Player B"
q) "Please moderator, ban him cuz he sounds mean by cutting to the facts"
r) "I'm just here to have my own problem solved, will take every response as to me directly, and will disappear as soon as I get the answer I want to hear"
s) "Let's take it to PM because challenging ideas and facts in the open is a waste of my time when all I want is an answer for my project"
t) "The 1990 book I bought on conversion off Amazon says to do it this way, so who the heck are these forum clowns pushing
lithium (they must be....they stated some facts I don't like about LiFePO/Pb, etc) and "AC" motors?"
u) "I'm going to take baby steps to learn and use i) a smaller pack ii) a lower voltage iii) multiple battery boxes to add more later, iv) use lead acid batteries; and ignore everyone here saying it will cost more, perform poorly, and double my build time"
