Indorerwamo yinyuma ntabwo ari indorerwamo iringaniye, ahubwo ni indorerwamo ya convex.Umwanya wo kureba indorerwamo yo kureba inyuma biterwa nibintu bitatu: intera iri hagati yijisho ryumushoferi nindorerwamo yinyuma, ubunini bwindorerwamo yinyuma, hamwe na radiyo igoramye yindorerwamo.Ibintu bibiri byambere byibanze bikosowe cyangwa bitagenzurwa, kandi ingaruka zigaragara cyane ni kugabanuka kwindorerwamo.Gutoya ya radiyo ya radiyo yubuso bwindorerwamo, nini nini yerekana umurima wo kureba, ariko mugihe kimwe, niko urwego rwo guhindura ibintu rwerekanwe, kandi ni kure cyane kuva kure, bishobora gutera byoroshye umushoferi.Kubwibyo, kugabanuka kwa radiyo yubuso bwindorerwamo bifite intera ntarengwa yagenwe ninganda.Iteganya kandi ko imyanya yo kwishyiriraho indorerwamo yinyuma yinyuma itagomba kurenza 250mm yimodoka.
