ah yes, the 0.3 meters difference in car length makes this completely “dishonest”. Throw the whole thing out because they used 4.5 instead of 4.2.

I don’t even get your point about car following distance. A line of totally immobile cars bumper to bumper is illustrative of nothing. Using the ideal scenario for car storage is hardly “more honest”. I have no idea what is motivating all this weird nitpicking.
