And the reason this has not been very seriously examined before is there was a common assumption in the industry that -- well, then it might not be safe if you got whacked by a heavy car, and it would cost a lot more to make, because the only way we know how to make cars much lighter was to use expensive light metals like aluminum and magnesium.
A razlog zašto ovo nije prije ispitano ozbiljno jest zajednička pretpostavka industrije kako onda ne bi bili sigurni u sudaru s teškim vozilom, i koštao bi puno više za proizvodnju, jer je jedini način na koji znamo raditi vozila puno lakšim upotreba skupih lakih metala poput aluminija i magnezija.
