I-American Insurance Institute, eyaziwa ngokuba yi-IIHS, inovavanyo lwe-bumper crash oluvavanya umonakalo kunye neendleko zokulungisa umonakalo ophantsi kwesantya esiphantsi ukulumkisa abathengi ngokuthenga iimoto ezineendleko eziphezulu zokulungisa. Nangona kunjalo, ilizwe lethu linovavanyo lokufikelela, kodwa umgangatho uphantsi kakhulu, phantse imoto inokudlula. Ngoko ke, abavelisi abanawo amandla okulungisa kunye nokwandisa iiplanga ezichasene ne-front and behind anti-collision ngokweendleko zokugcinwa kwe-low-speed collision.
EYurophu, abantu abaninzi bathanda ukuhambisa indawo yokupaka phakathi kwangaphambili nangasemva, ngoko bafuna ukuba imoto yomelele ngesantya esiphantsi. Bangaphi abantu eTshayina abaza kuhambisa indawo yokupaka ngolu hlobo? Kulungile, ukuphuculwa kwesantya esisezantsi sokungqubana, kubonakala ngathi amaTshayina akazukufumana.
Ukujonga ukungqubana kwesantya esiphezulu, i-IIHS e-United States kunye ne-25% yezona zintlukwano ze-offset zehlabathi, ezi zilingo ezinzima zinceda abavelisi ukuba banikele ingqalelo kwisicelo kunye nomphumo we-anti-collision steel beams. E-China, ngenxa yemigangatho ye-C-NCAP ehlwempuzekileyo, abanye abavelisi baye bafumanisa ukuba iimveliso zabo zinokufumana iinkwenkwezi ezi-5 nangaphandle kweentsimbi zentsimbi, ezibanika ithuba lokuba "badlale ngokukhuselekileyo".
