N’chifukwa chiyani pali nyali imodzi yokha yakumbuyo ya chifunga?
Pali umboni wa sayansi woti pali nyali imodzi yokha yakumbuyo, yomwe imayikidwa mbali ya dalaivala, kuti galimoto ikhale yotetezeka kuyendetsa. Malinga ndi malamulo okhudza kuyika magetsi a galimoto, nyali imodzi yakumbuyo iyenera kuyikidwa, pomwe palibe lamulo lokakamiza pakuyika nyali zakutsogolo. Ngati ilipo, nyali yakutsogolo iyenera kukhala ziwiri. Kuti muwongolere mtengo, mitundu ina yotsika mtengo imatha kuletsa nyali yakutsogolo ndikuyika nyali imodzi yakumbuyo. Chifukwa chake, poyerekeza ndi nyali ziwiri zakumbuyo, nyali imodzi yakumbuyo imatha kukonza chidwi cha galimoto yakumbuyo. Malo a nyali yakumbuyo yakumbuyo yomwe yayikidwa ndi ofanana kwambiri ndi a nyali ya brake, zomwe ndizosavuta kusokoneza mitundu iwiri ya nyali ndikuyambitsa ngozi zachitetezo. Chifukwa chake, nyali imodzi yokha ya chifunga ndiye chiwonetsero chabwino cha chitetezo cha galimoto.
