Ina hoko waka hiko ngā kaihoko, ka whakataurite rātou i te tere whakatere, te kaha o te pākahiko me te manawanui o ngā pūnaha hiko e toru o ngā waka hiko. Nō reira, kua whānau mai he kupu hou "manogi maero", arā, kei te manukanuka rātou mō te mamae hinengaro, te manukanuka rānei i puta mai i te korenga o te hiko i te wā e taraiwa ana i ngā waka hiko. Nō reira, ka taea e tātou te whakaaro ki te nui o te raruraru i pā mai ki ngā kaiwhakamahi nā te manawanui o ngā waka hiko. I tēnei rā, i whakapuaki te Tumu Whakarae o Tesla, a Musk, i ana tirohanga hou mō te maero i te wā e kōrero ana ki ngā pā i runga i te whatunga pāpori. I whakaaro ia: kāore he tikanga o te maero teitei rawa!

I kī a Musk, i taea e Tesla te hanga i tētahi tauira S e 600 maero (965 km) te roa i ngā marama 12 ki muri, engari kāore i tino hiahiatia. Nā te mea ka kino ake te whakaterenga, te whakahaere me te whai huatanga. Ko te tikanga o te nui ake o ngā maero ko te whakauru i ngā pākahiko me te taumaha ake o te waka hiko, ka tino whakaiti i te wheako taraiwa whakamere o ngā waka hiko, engari ko te 400 maero (643 kiromita) ka taea te whakataurite i te wheako whakamahi me te whai huatanga.

I tukuna tonutia e Shen Hui, te Tumu Whakarae o te waitohu motuka hiko hou o Haina, a Weima, tētahi blog iti hei whakaae ki te tirohanga a Musk. I kī a Shen Hui "ko te manawanui teitei ake e ahu mai ana i ngā pākahiko nui ake. Ki te oma ngā motuka katoa i runga i te rori me te pākahiko nui i runga i ō rātou tuara, ki tētahi taumata, he maumau noa iho". E whakapono ana ia kei te piki haere te maha o ngā puranga utu, kei te piki haere te maha o ngā huarahi tāpiri pūngao, ā, he pai ake te whai hua, he nui hei whakakore i te manukanuka utu o ngā kaipupuri waka hiko.
Mō ngā wā roa o mua, ko te maero pākahiko te mea tino nui i te wā i whakarewahia ai ngā hua hou e ngā waka hiko. He maha ngā kaihanga i whakaaro tika ki tēnei hei mea nui o te hua me te ara whakataetae. He pono he tika hoki te tirohanga a Musk. Ki te piki ake te pākahiko nā te maero nui, ka ngaro te wheako taraiwa. Ko te kaha o te tāke wahie o te nuinga o ngā waka he 500-700 kiromita, he rite ki te 640 kiromita i kīia e Musk. Te āhua nei kāore he take e whai ai i ngā maero teitei.
He mea hou, he mea motuhake hoki te tirohanga he nui rawa te maero. He rerekē ngā tirohanga a ngā kaipāho ipurangi. He maha ngā kaipāho ipurangi e kī ana "ka taea e te maero teitei te whakaiti i te maha o ngā wā o te manukanuka manawanui", "ko te mea nui ko te kore e whakaaetia te manawanui. Hei tā te 500, he pai te haere ki te 300. E kī ana te kaipuke tāke he 500, engari ko te mea pono he 500".
Ka taea e ngā waka tuku iho te whakakī i te tāke wahie i roto i ētahi meneti i muri i te whakaurunga ki te teihana wahie, engari me tatari ngā waka hiko mō tētahi wā kia whakakīia te hiko. Inaa hoki, i tua atu i te maero, ko te mahi whānui o te kiato pākahiko me te whai huatanga o te utu te pūtake o te manukanuka maero. I tētahi atu taha, he mea pai anō hoki kia nui ake te kiato pākahiko me te iti o te rahinga kia nui ake ai te maero.
