telephoto lenses tend not to look too bad with USA roads because the roads are straight, wide and have traffic lights, so they simply move the view further forward
During the almost ten years that I have known you on this forum, Nigel, you have continued to put forth imagined false stereotypes about the USA which most of us here find insulting and offensive. You seem to exist basically as some conspiracy theorist putting out one imagined false narrative about the USA after another. It is part and parcel with your regular and ongoing nation bashing towards the USA, as literally all the false stereotypes and narratives you put forth are negative to one degree or another, even this rather mundane one. One truly has to wonder how and where you get your notions about what things are really like in America (and other countries you've never visited that you tend to comment on as if what you have to say is factual). As I have often been compelled to point out to you the United States is an enormous and diverse country with countless different environments, road types, traffic conditions, climates, peoples, cultures, etc., etc. etc.
And to the case in point, despite your false stereotyping to the contrary, the USA has some of the most curvy, bendy, winding roads on the planet depending on where you happen to be!
Here is some old footage of a winding road I travel on a daily basis. There is not a straight stretch of road literally for many miles! Roads like this in mountainous parts of the country are fairly typical, especially here in northern New England.
And going back to your original imaginary and false comments, Nigel,
NO! .......telephoto lenses on dash cams do not create any illusion that you are driving at speeds any faster than normal or seem any different than your rate of travel would appear in a video from a traditional dash cam with a typical lens focal length.
Again, as I've already pointed out you apparently have no personal hands-on experience using telephoto lenses on dash cams, so where do you come off making these sort of imaginary false pronouncements? You appear to simply be making things up.
Here is a typical telephoto dash camera video to have a look at. Does it appear as if my vehicle is traveling faster than the posted speed limits? NO!
Does watching the video make viewers feel sick or scared? NO!
Is the video shot on a winding, curvy road? Yes!
P.S. If I get some time today, perhaps I will update this footage with something more current.
