There is a lot of mockery in this thread.
But I have to flip the question back to you.
The consensus is that the earth is round and rotates at 15° per hour.
This has been even been proven by experiments conducted by various flate earth societies (see Behind The Curve documentary on netflix).
In addition, all the ISS Space Walks and rocket launch live streams that show curvature beyond the typical "lens distortion" arguments.
And the video footage dating back 50 years of the earth, looking very globe-like (no government is efficient enough to hide such a broad conspiracy for such a long time, without ANY leaks).
So, why do YOU think the earth is flat?

Wiki to the rescue!
It's a great video from 1937.
And the article has info as well https://en.m.wikipedia.org/wiki/Differential_(mechanical_device)
Modern cars have "traction control", which detects when a wheel turns more than the other wheel. If it turns too much more, it will engage a "diff lock" and lock the differential which makes each wheel turn with the same power/speed/energy as if the differential was just a solid axle.
The long & the short of it is that a differential is only "1 wheel drive" when the differential "thinks" (it's not smart) it should put all the power into 1 wheel - which is when the cars computer locks the differential.
