Perbedaannya sepertinya lebih jelas di situs ini:

Ride-hailing is when a rider “hails” or hires a personal driver to take them exactly where they need to go. The transportation vehicle is not shared with any other riders, nor does it make several stops along a route.

Ride-sharing, by contrast, is synonymous with carpooling. It is literally the process in which a rider shares a vehicle with other riders. It is not personal transportation, as the space is shared, and it will make stops to pick up other riders.

✅ Proses keduanya saat ini sama saja: pesan lewat peranti seluler/internet. Bedanya, RS bersama-sama, RH pribadi.

🚕 Jadi, RH tidak lebih daripada takdar (taksi daring). Jika dahulu kita menyetop taksi/mobil sewaan di pinggir jalan, sekarang kita meminta dia datang ke tempat kita menunggu. Persis taksi, sekadar ditambah TI + tahu biayanya sedari awal.

🚕 Sementara itu, karena pada RS para penumpang menyumbang biaya sewa agar lebih murah bagi masing-masing, kita bisa gunakan kata urun.

Alternatif-alternatif RS vs. RH
1-urun takdar vs. sewa takdar (menekankan sifat daring/online dalam pemesanan)
2-urun takol vs. sewa takol (mengikuti pola ojol/ojek online, walau penutur bahasa Sunda bisa salah paham, sewa/urun pukulan).
