E-China, kukho malunga namashumi amawaka ababoneleli be-high-speed guardrail abathumela ngaphandle, kuquka iinkampani zorhwebo kunye nabavelisi.Ngenxa yokungabi nalwazi lwangaphakathi lwefektri, uninzi lwababoneleli bakhona njengeenkampani ezirhwebayo ezinabasebenzi aba-1-5, umlinganiselo wabo uphezulu ukuya kutsho kuma-91%, kwaye balungile ekuzipakisheni njengefektri okanye abavelisi nge-Intanethi kunye neqonga lomntu wesithathu.Kuphela i-9% yabavelisi banokuba neenzuzo zexabiso kunye nokukwazi ukulawula umgangatho.Ke ngoko, kwiikontraka ezininzi ze-high-speed guardrail zangaphandle okanye amaqela okwakha, kubaluleke kakhulu ukwenza uphando ngasemva kwenkampani phambi kokuthenga, kuba kuya kongela iindleko kunye nexesha.

Kodwa eyona nto ibhidayo kukuba kusekho iinkampani ezininzi zokurhweba ezivelayo, nto leyo eyandisa imiqobo kubathengi baphesheya kweelwandle beetrayile ezinesantya esiphezulu ukuze bakhuphele abavelisi abanamandla okwenyani, ke ekugqibeleni ibuyele ekuqaleni: iitshekhi eziyimfuneko. iya kuzisa inzuzo kubathengi.ukonga iindleko ezinkulu.
