I was just making the point that justifying swerving out due to some undefined 70 mph effect is incorrect if you don't know what you're dealing with. And that whoever came up this 70 vs. 35 mph effect justification should realise that it mostly applies to e.g. the truck example you gave and somewhat to cars of significantly different mass / size. Therefore it's confusing advice and obscures other possible good reasons for swerving out.
