The spring steel in a truck and the load rate and type and the way they work are totally different than those exerted in a firearm magazine. You can't compare the two. On that note....I have been shooting and have owned 1911s since about 1975, I always leave my mags loaded to capacity and they have never failed or even had any noticeable change in any way nor have any of my AR mags which I have also owned and used since 1978.
