Being fair, either one of those is grossly out of proportion, or the prototypes are entirely different and thus it's a bit of an apples:oranges comparison. Assuming a 4.3m high lorry it would be 29.05mm in 1:148, 28.67mm in 1:150 and 26.88mm in 1:160, ie the difference between 1:148 and 1:160 is just over 2mm or less than 10%. A difference, for sure, but that photo massively over emphasises that.
